The listing, Tony Hawk's Underground 2 PC CD-ROMs has ended.
Fun skating game for PC, with online multiplayer mode (I do not know if the servers are still up for online play, but it's awesome offline anyway). Includes jewel case with serial and 3 discs (I believe these are all the CDs but it has been a long time since I played this and I could be mistaken). If I find the manual and outer box before time to ship, I'll include those as well.
