IDK what games are actually compatible with your device, but I do have opinions about cool older games.
turn based:
Civilization
Master of Magic
Champions of Krynn, Death Knights of Krynn, and Dark Queen of Krynn
Shadowrun Returns, Shadowrun: Dragonfall, and Shadowrun: Hong Kong
Arcanum: Of Steamworks and Magic Obscura
Not sure what they have available, but Advance Wars and Tactics Ogre I both had fun with. I heard good things about the Disgaea games (the fourth one in particular), too, but never played them.
I've been going through the old Final Fantasies. I finished FF5 and FF6 last year and recommend both. They have great pacing (They change things up before it gets too stale) and if you keep an online guide handy, it's not as frustrating as it was when I was 10.
Cannot recommend Panzer Dragoon Saga enough. One of the best looking Sega Saturn games. Its a JRPG with turn-based battles, a super unique system. Along with the rest of the Panzer Dragoon series (though they are on-rails arcade shooters), not sure the RP3 is powerful enough for original Xbox games.
For driving, I am sure you've already been recommended the usual, but to reiterate: anything from Gran Turismo, Star Wars Episode 1 Racer, Collin McRae, WipeOut, Need for Speed, and Sega GT are all good picks.
