The Buck Rogers games from SSI never were rereleased on CD-ROM, AFAIK. The Dragonlance trilogy of Gold Box games were included in Wizardworks' "shovelware" CD-ROM compilation of Gold Box games in the mid-1990s. The Forgotten Realms quartet & Savage Frontier duology of Gold Box games were rereleased both on the Wizardworks CD-ROM and on various CD-ROM compilations from Interplay from about 1997-2001.
I think GOG.com should carry at least the 2 Buck Rogers games, and the fantasy-themed Gold Box games as well (if possible).
T.A.P.: I'd really love to get all 7 of the Commander Keen games and the old TSR Gold Box series RPGs.
I really want to play the two Buck Rogers Gold Box games as well as the D&D ones. Did Hasbro get the rights for them when acquired D&D/TSR?
