I would have preferred more meaningful singleplayer content. Can't imagine multiplayer without a mouse. There's apparently a tournament mode but why not a "fun story mode where you fight your way to the world championship match"? "100 bonus puzzles"? That's great, I can solve those in 20-30 minutes. There's huge tactics databases out there, so why not get 20 000 puzzles? Solving those on the GamePad would be great. There's unlimited possibilities for modes, e.g. get a database of master games and let the player play "Guess-The-Move", implement opening training, essential endgames, etc.
Don't know how the feature set is otherwise, like, which chess variants can I choose, what customization options are there for the board, etc. Speaking of which, all those 3D boards are completely useless, and I haven't seen a single 2D option in the footage that's out there (can't imagine it not being in there, though, but it, again, makes me wonder how customisable it will be).
Anyway, I realise I sound way bitter about this, but hey, I just want a decent chess game that's not sterile as hell. Seems like nobody that's actually into chess is ever involved with these.
