I'm talking real old school- like 1989 and before. My favorites were Seven Cities of Gold, OrbQuest (anyone else get their hands on that one?), NFL Challenge, Crystal Raider, Arkanoid, MicroLeague Baseball 2, Sim City, Hardball!, Transylvania, Dungeon of Doom, Scarab of RA. Man, those were some good times! Here's to Worldbuilder!
