1. Kerbal Space Program ; This game changed my understanding of the universe. No other video game, let alone one in 2015, can begin to claim that. As hyperbolic as that may seem to some, it really only scratches the surface of what makes KSP phenomenal. Every space video game, sci-fi movie, NASA video, Space X live stream, Pluto news article, etc is illuminated in a completely new light thanks to my time with KSP. What KSP taught me, has given me an entirely new appreciation of mankinds achievements in space. Everytime I look at the moon or the stars, I have a better understanding of how they move, and why they move that way. Its as if KSP taught me a new language, and in a sense it did. The universal language of orbital mechanics. What is truly amazing about KSP, is not that it ends up teaching you about the fundamentals of orbital mechanics or rocket design, it is how it imparts that knowledge. The innocent little green Kerbals and the countless ways they can meet their untimely demise, softens the learning curve. You can have hours of entertainment barely leaving the launch pad in one piece. However, as you improve and set new goals, you begin to digest each new step required to get into space, but more importantly how to make them to stay there.
Any game could give you a wall of text explaining orbital mechanics, but KSP does it through addictive and rewarding gameplay. Each success is met with the desire to push yourself further. KSP doesnt rely on loot, rankings, or unlocks to incentivise the player, it utilizes humankinds innate desire to explore the cosmos. The first time I successfully landed on the Mun, the satisfaction and sense of accomplishment I felt, far exceeded the thousands of trophies and achievements I have earned in video games up to that point...combined. It is a truly astonishing game that I will play for the rest of my life. I recently became a father, and I look forward to sharing gaming with my son as he gets older. The list of games that I absolutely cannot wait to play with him is one entry long, Kerbal Space Program.
2. DiRT Rally ; 2015 had several sleeper hits, and DiRT Rally is one of them. From a rather quiet early access to an abrupt 1.0 release, DiRT Rally wasnt on many peoples radar. However, once word started to circulate, it was unanimous praise. DiRT Rally is the best game Codemasters has released in almost two decades. Moreover, it is arguably the best rally game since the much coveted Richard Burns Rally. DiRT Rally returns the series back to its more pure, hardcore rally roots, and it is better for it. The sport of rally racing has adrenaline and excitement by the piston full. There is no need for over the top physics-defying speed, boost buttons, artificial motion blur and DOF effects. All you need is some pacenotes, highly detailed rally stages modeled after their real world counterparts, and the incredible machines that have raced down them for half a century. There is nothing quite like being in the zone in DiRT Rally. When you know you need to push on the final stage, and that the smallest lapse in concentration is all that separates you from victory or a race ending crash, you experience a thrill seldom achievable in gaming. I expect to see this game back on lists in 2016 as it launches on consoles.
3. Rocket League ; I love cars. I love soccer. Yet, Rocket League still completely blindsided me with its brilliant and addictive gameplay. It is rare that a game can seamlessly blend easy pickup and play mechanics with high level eSport worthy depth. You can grasp the concept of the game instantly, but mastering the skills of aerials and other high level tricks will keep you coming back night after night. I love playing this game with friends and on my own. I can play one match or fifteen in a session and still walk away satisfied. I expect this game to stay in my play rotation for several years.
4. Tom Clancy's Rainbow Six Siege ; Even though I placed DiRT Rally higher (race sims are my favorite genre), Rainbow Six Siege is without a doubt the sleeper hit of the year. I cooled on Tom Clancy games ages ago, but I always liked little bits of what I saw in them. Tactical FPS gameplay has always been appealing, but the format was never quite right for me. Other than the occasional banner on PSN, I had no idea this game was even out, let alone how fantastic it was. Thanks to an enthusiastic GAF thread, I began to watch some videos and streams of gameplay and I immediatly realized this was the SWAT meets Counter Strike game I have been dreaming about since I was kid. Rappelling upside down, breaching through walls, swinging in through windows just after a flash bang pops, the list of gameplay moments that make you grin ear to ear while feeling like a bad ass are near endless. The sound design is also incredibly well crafted. When you have a pair of headphones on, and you hunker down to defend and room, you can sense player movement like some sort of acoustic wall hack. As the tension rises, and the sounds of the attacking players close in on you, you feel a sense of suspense that only the best thriller movies can achieve. Ubisoft could have packaged and marketed the game a bit better. The reward and unlock structure being nearly verbatim to Heroes of the Storm, a free-to-play game, does not make a strong first impression after you just paid $50, but dont let the cover put you off the book. Siege is not only the best FPS I have played in years, it is also the only FPS I have enjoyed PvP in since COD4.
5. Helldivers ; This top down co-op game comes off as a simple twin stick shooter, but the depth and fun Helldivers can deliver is commendable. The always on friendly fire combined with the clever stratagem system makes for tense gameplay moments as well as hilarious laugh out loud failures. The Starship Troopers tone of this game is a perfect match for the mechanics and game design. I loved every moment I had with Helldivers. Spreading democracy throughout the galaxy has never been more enjoyable.
6. Heroes of the Storm ; This is the first MOBA I have ever played. That says it all. I had a blast playing HotS, and it was the only game to ever bring me into the MOBA fold and finally understand what people have been going crazy about for years.
7. Destiny: The Taken King ; Too little too late is how I would sum up my time with TTK. It was great to have a deluge of new content that made Destiny fun again, and running the new raid with my buddies was once again top notch gameplay and a truly unique experience. However, a lot of the same bullshit from year one began to slowly come back and the new content eventually dried up. I am onboard for Destiny 2, but I dont see myself returning until then. The end game still feels like an exploitative job more than a fun game.
8. iRacing: Nordschliefe ; Adding a single track to a racing game may not seem like a notable release, but this is the Nordscliefe in iRacing. Its not just that iRacing created a stunningly accurate representation of The Ring, other games have very accurate versions as well. It is the fact that you finally get to experience this track with iRacings cars, physics engine and their unrivaled online racing platform. I have logged literally thousands of laps around this track across a dozen racing sims through the years, but iRacings version still managed to make it feel new and cause white knuckles all over again.
9. Grow Home ; I heard good things about this game, but it wasnt until it was free on PS+ that I finally gave it a try, and I am happy I did. The first few minutes of Grow Home had me thinking, I dont get it. It was when I was a few thousand meters up, hanging on the bottom side of a rock with one hand, looking down, when I realize how cool this game is. Fun QWOP-like controls combined with the marvel of open world 3D platforming I havent felt since Mario 64 plants Grow Home firmly in this list.
10. Undertale ; A fun throwback RPG that subverts your expectations of all the JRPGs you played growing up. Great writing and clever twists make this game charming and memorable. The bullet hell mechanics, although cleverly integrated into the game, put me off enough from ever wanting to try a second run, but that first time through was great.
Honorable Mentions
x. Cities: Skylines ; Everything Sim City should have been and then some. I just wish this game came out first so I didnt waste all of my city designing efforts on the inferior game.
x. Fallout 4 ; It is an improved version of Fallout 3, but not different enough. I hit the same Bethesda open world wall where I find little to no motivation to return to the world or finish the main story. Sometimes less is more.
