This is Portabliss, a column about downloadable games that can be played on the go. Star Wars Knights of the Old Republic is the kind of game that's almost too big to be playing on the iPad. It's easily 30 hours long, with extensive attribute, skill, and combat systems, and it has some of the best storytelling BioWare's ever done, all set in the epic pre-film Star Wars universe. This is a monster of a classic game, and like Grand Theft Auto: Vice City and Baldur's Gate before it, it seems like cheating to play this game on Apple's touchscreen tablet, like you're somehow breaking the laws of mobile gaming physics, if such a school even exists.

And yet, it works. Aspyr Media is the company responsible here. It's been porting games to the Mac for a long time, and with Knights of the Old Republic has decided to start bringing what it calls "catalog Mac experiences" to iOS. Presumably, the rights were snagged from BioWare and LucasArts, and now there's a very well-made $9.99 port of one of the best Star Wars games ever assembled, running on the iPad.
