I am only around chapter 5 or 6 of Rebirth (in Costa del Sol), but I feel a little crazy, my impression is that Remake actually hits harder in the story bits than Rebirth, and so far I think I like that one more.
I feel like Rebirth will be a great game in the end for me, but also perhaps a little disappointing. I just don't feel the urgency I was expecting with anything in this game, but I do enjoy the cast, and the gameplay. The side characters, they're a big let down for me. They range from damned annoying to looking like they were stuck in for diversity purposes to just being unimpressive.
Visually the game isn't that great either, but I do appreciate that there's an actual RPG to play here, unlike in FFXVI, and trying to get the different parts for the Gilgamesh summon by exploring around the open world sections so far is the highlight of the game. Gold Saucer should be a lot of fun too I hope.
