Just received my copy and I decided to start of with Re:CoM.
30 mins into the game and I've already encountered Sora's creepy smile multiple times lol.
Voice acting in CoM doesn't feel right either. Axel doesn't say "Got it memorized?" like he does in KH2 and Days and Donald is just so awkward but that might just be me from not hearing him for so long.
Despite these things, I'm enjoying the game and the HD-ness looks very good.
