Diablo 2: I lived off that game back when it was first released. I blame it for making me almost fail high school.
Starcraft: See above.
Plants vs Zombies: Don't judge me!
Final Fantasy XI: One of the few MMO's I've stuck with for longer than a year.
I think I remember that... it was in the orange box, right?
That is correct!
This is a Triumph. Making a note: huge success.
Starfleet Command (the first one)
Mechwarrior 2: Mercenaries
Dungeon Hack (wwaaaaaay back on that one)
Kings Quest VI
Space Quest...IV, I think. The one with the mutant blob monsters.
Treasure Mountain (hey, for a 3rd grader on an XT, it was mind blowing)
