What would really make my day is a port of Anki. Not at all a game, but a practical flashcard making resource with single button, built in voice recorder and a P2P network with hundreds of language quiz packs.
I did a search on the forums, and someone had already suggested porting it I believe, but it was brushed over because it has an online version. Said online version is a hundredfold inferior to the downloadable version, with missing features like statistics and separately tagged card decks.

It is open source and already has respectable android and iPhone ports, but a Pandora port would make not only my day, but my entire semester. I've been living off this software to get through Spanish IV and Biochem, and a portable version would be one of the best things EVER.
If there is no initial interest, I'd be willing to front some cash into this venture, but I hope it doesn't come to that.
