Well.. they created...
Bram Stoker\'s Dracula (SNES, Genesis, Game Gear, and I think for the Gamboy)
Cliffhanger (NES, Gameboy)
Equinox: Solistice 2 (SNES)
ESPN Baseball Tonight (Sega CD)
ESPN National Hockey Night (SegaCD, Genesis)
ESPN NBA Hangtime \'95 (SegaCD)
ESPN Sunday Night NFL (SegaCD)
Hook (SegaCD, NES)
Last Action Hero (Genesis)
and Smart Ball (SNES)
Now that\'s not a really incomplete list, but it\'s the best one I could find on short notice. (Gamers.com + IGN.com) They also published a whole host of other games.. but they don\'t count since Sony Imagesoft just published them.. they didn\'t create them. Personally, I\'ve only played the Genesis and GameGear versions of Bram Stoker\'s Dracula. They weren\'t AAA games, but they were fun none-the-less.
Happy Rom hunting.
