The CD case was all warped due to heat, the CD didn't survive either :/
How long was it there? Some years, i think
When I was in my teens I played Mechwarrior, a LOT, with my friend Dan. I don't remember what version it was at the time, but it was early on. One of us would build a Flea and try to take down the other in an ultra-heavy mech.
Dan died about 2 years ago. I just went on an emotional roller coaster for a few minutes. Hug your friends.
