Not listed in any order because I just can't do it, and they're all completely different games to boot.
Castlevania SotN (psx) - One of the best platformers ever.
Chrono Trigger (snes) - Great all around RPG. Story, graphics and sound were amazing for it's time.
Total Annihilation (pc) - One of the few games that never leaves my hard drive. I only wish more people played it. WAY ahead of it's time. Can't wait for Supreme Commander.
