Recently I grabbed a cherry copy of the Buck Rogers Adventure Game (or High Adventure, not sure which) on Amazon for what seemed like a reasonable $25.
TSR seems to have produced a number of really innovative games that for the most part went underappreciated, unnoticed or simply disliked back in the 90's and this is, I think, one of them. Although it's understandable why there is no love for this game (the Williams Taint again) and it came off to most gamers of the day, myself included, as pretty bizarre considering the failure of the previous Buck Rogers game.
