The beginning is pretty much chill, with the group hanging on the beach resort, eye candy included. I always love these kind of chapters in Trails, there are a lot of interesting character interactions since a lot of the cast is condensed in a single location. The Connect Events were really good, absolutely do not skip them and save/reload to see them all, it's worth it.
The second day is where things start to get serious. We are forced to be involved with Harwood's plot which leads to tons of fun fights against all the other factions. The fight against Shizuna was tough as nails but I managed to scrape by... and after that she goes like "thanks for the warmup", lol. I will never understand Trails power scaling.
The climax was great, lots of Dead Ends and lots of stuff happening: finding out that this is in fact Paradise, which ties with the whole Renne's subplot. Then the discovery about Quatre and his angelic form, then the fight against Ixs/Jorda (they are crazy but I love 'em), followed by Harwood being Harwood (he's a fun villain) and the appearance of the Gardenmaster (what a dumb name)... One thing after another, holy shit.
I didn't expect Swin betraying us and stealing all our Genesis fragments. What the fuck are you doing my man. Poor Nadia.
I still have no clue what the Geneses are for, but I guess we will see by the end of this game.
