Be it about the game's plot and characters, the mechanics, or what to do if I get stuck - anyone got anything I should know? Only played P4G before. Got about 60 hours into that one, but uninstalled when I had to lose all my gear (hate that mechanic)
Exploiting enemy weaknesses is pretty key to winning on the RPG side of it. It's not a particularly difficult game, though, so I think it's best to just sit back and enjoy it.
