So, I just finished Final Mix. I'm currently playing through on Re: Chain of Memories on proud, but I think I may come to regret this decision because I am bad with strategy.
I'll probably restart with beginner, only because I need some time to get used to the new system.
I am a bit perplexed with how the room system works though, is it important what card choices you make for the doors? Will I be losing anything if I just use a normal card, rather than something special (such as items and special 'must have' drops)?
