Hey, free, you should really try a few SCUMMVM games. (Monkey Island, Indiana Jones series, Gobliiins - works beautifully in the IT and it's still a lot of fun, Full Throttle - if you can get ahold of the full version).

I've even played Leisure Suit Larry on the IT, but without the USB keyboard it's a PITA.

I've been playing these few in the IT and it's incredible how well crafted these oldies goldies were.
