Well, as i said before in another thread, there are Shareware versions, older versions (1.22, for example), versions by other publishers (Europeans don't have GodGames distributions, for example, or the mysterious "Black Friar" versions from the UK), Demos (TSF!), OEM, Beta and unfinished versions. But you're right, JJ1, JJ2, HH98, TSF and CC99 is all you can *BUY* (hard to get them in stores nowadays though).
Not to mention the legendary "your friends will turn green"-T-Shirt, the J2 T-Shirt, my P2 TSF mousepad and so on.
By the way, if you guys have one of these (hey Shad), make some photos and post them here :-)
