I don't collect them. I only get the ones I want. However, if I could actually get a sealed Dark Forces for a reasonable price, I would leave it in it's packaging and display it somewhere. I'd probably get Kyle and my Darktrooper action figures in front of it. I love that game so damned much. Some would say it's an unnatural love
Here's the games I have:
PC
Dark Forces
Jedi Knight: Dark Forces II
Jedi Knight: Mysteries of the Sith
Jedi Knight II: Jedi Outcast
X-Wing Alliance
Galactic Battlegrounds (I don't like this game too much, it was fun the first time through but has no replay value)
Rogue Squadron (I hate this game, never finished it)
Episode I: The Phantom Menace (I hate this one even more, I quit once I got to Coruscant)
XBOX
Knights of the Old Republic
Jedi Academy
