i've only watched a lets play of Xillia 1&2 and they were decent I supposeIf you have a PS3/4 then you should try out Berseria. It's pretty damn good and I feel the characters and story are a huge part of that. Plus it's battle system is a lot simpler than past games.
Tales of Graces F. I liked the flow of combat more in that game than Xillia and Xillia 2, which are the only other games I've played. This is probably due to the lack of MP in that game, meaning you can just spam your power attacks and not really get punished for it. I also like the story better than Xillia, but maybe that's because I haven't beaten those games yet thanks to certain bosses being annoyingly hard.Tales of Graces f is pretty alright though I'm not able to finish it due to some problems with my PS3 controllers. I prefer Xillia 2, but that's just me.
I've always wanted to play Vesperia and Abyss but I lack a 3DS and a 360 to play them on. Maybe I can find a PS2 copy for Abyss or something. And I agree with you on Berseria's characters.Abyss also has an Anime, which is okey, but I like the game more. Vesperia on the other Hand, the movie sucked. The game is good.
