How do you mention the quest games, but leave off Quest for Glory(So you want to be a hero?)? That one had great comedy and references all through it, and each of the series linked to the next so you could continue to progress your character through them.
Also well up there:
Fallout 1&2
Baldurs Gate
Planescape: Torment
Freelancer
Sacrifice(great 3rd person/rts, you choose your faction each mission and it shifts your story)
Swords and Serpents
