Um, aren't ANY of you interested in the Kingdom Hearts game? I for one really enjoyed the PS2 game, and I think the GBA version could be pretty fun as well. I hope Donald and Goofy follow you around, but I'm not sure if they will...
Reason being that this game involves card battling of sorts (possibly like Mega Man Network Transmission - a limited number of special attacks, and battles in real-time), plus one screenshot showed Goofy in the center of the screen doing his shield-spin, with a Goofy card selected, while Sora held his keyblade straight up. In other words, it hinted at Goofy being a summon, or the player controlling him perhaps.
I thought the PS2 Kingdom Hearts was really fun, and I've beaten it 5 times already, so I have good authority to hold such an opinion. I hope this game keeps that type of fun and the fast paced and frantic battles as well.
