Chain of Memories Which was harder: CoM or Re:CoM?

reaction commands are just for follow up attacks like in Sora's Sonic Rave and reaction command is used for Riku's duel attacks.

but anyways, the GBA version was MUCH harder. they made the enemies take too much damage in RE: COM, the fights didn't last as long as they needed for it to be hard. if the fights just lasted longer i'm sure that the game woudl be tougher. also, in RE:COM, Riku can use Mickey's card while fighting Riku Replica in Twilight Town which is a change from the GBA version when you couldn't.
