Well, to change the subject back to the topic ;), Revolution may have the games best sellers with a new Smash Bros and Zelda coming out.(The one coming out for GCN).
As for game capabilities on Revolution goes...it has the most. Being able to play old games from SNES, N64, and NES will make for better change in playing on the CPU with emulators.(Even though everyones played most of the games already) Also being able to play the GCN games on it too is a big plus while still being able to play the new games it has coming out on regular sized disks.
And i don't know about you but playing alll the RPG's I've played on Emulators, and it would be better with to play better screen, sound, and controller.
