I must be a super minority. I see almost no redeeming value in the Halo series. The game play feels very dated, and technically the games weren't very good either. Upscale graphics just to reach 720p.
Color me unimpressed with Bungie.
Feels like most people I know that really like Halo, are a tad younger or just didn't grow up playing any MP games, because it feels highly reminiscent of Quake and a few other games blended in.
The fact that they made so many of them blows my mind (particularly that people bought it up in droves). Don't get me wrong, if you've never experienced that style of game it's what can get people into gaming, but it's really interesting that people stuck with the series when there is objectively better shooter experiences available.
