My favorite COMPUTER games are basically any adventure game from LucasArts including: Maniac Mansion, Day of the Tentacle, Indiana Jones and the Fate of Atlantis, the Monkey Island series, Loom, Sam & Max Hit the Road, etc. These games are just chocked full of humor, pop culture references and challenging puzzle-solving game play. I love Sierra games as well, but LucasArts game always offered more FUN.
My favorite CONSOLE games are Earthbound and Final Fantasy VI both on SNES. I'm a huge fan of JRPGs, so those are the games I play more often, however, I do also LOVE NES Capcom platformer games like Mega Man, DuckTales, & Chip N Dales Rescue Rangers.
