This list is more for me than you, but you can tell me which one(s) to play next. It's just a list of games I've bought but haven't played, in no order.

MOH: Pacific Assault

MOH: AA: Spearhead + Breakthrough (I played the original)

MOH: Airbourne

NFS: Underground 2

Fallout Tactics

Some Rally DOS game

Some Star Wars DOS game

Star Wars: KOTOR 2

Star Wars: Online

Codname: Outbreak

FIFA: 2002

Soldier of Fortune

They're off the top of my head, I could bet you I have more; so I will update this list if/when I find out.
