I used to be more of a PC gamer.... so definitely a fan of the Sim City games... from the original to Sim City 4... after that, I lost interest... Played SimTower a bit... SimPlanet was interesting.... Basically any Chris Sawyer game (Transport Tycoon 1 & 2 Deluxe... Locomotion... Roller Coaster Tycoon 1-3...)... Lots of Warcraft/Starcraft (not the online crap, the build a city, defend yourself, go kill everyone kind)... oh yeah, and Diablo 1 & 2... hope the 3rd is just as good/better....
On the console side... I've been playing Fable recently... Fable III was free with my xbox live sub, so I played it all the way, then found Fable II at GameStop for cheap... besides that, all of the Prince of Persia games (except maybe the oddball one with the Califonia Surfer dude prince)... Most of the Zelda games, Mario Bros, etc...
