One GameCube with a Gameboy Player on one TV, connected to another GameCube with Final Fantasy: Crystal Chronicles on another TV. Dual Screens on a whole new level.
What does it matter if it's only 20 hours long? At least it was all worth it. When you play a game like Final Fantasy VII, you beat it in 40 hours but 20 hours of that is just some shitty random battles.
Also the fun in FF:CC comes from the multiplayer and collecting the artifacts and all those special items/weapons, not from just beating the game. I've played 2 player game with my friend for 85 hours and it's been fun (he's also played it single player for over 110 hours and I've played it single player for over 45 hours).
What I played of the multiplayer of FF:CC, was some of the best team-based RPG multiplay I've experienced since Secret of Mana. If Square refines this sucker for Rev launch, then it really could be absolutely killer.
