@skateblind - If you've played Bard's Tale, just imagine that but with a totally different campaign setting. You also needed to consult a printed journal frequently for flavor text. It remains a cult classic, though not nearly as well known as Fallout of course. I believe that some of the folks who worked on Wasteland also worked on Fallout.
@adropac2 - Seems funny that people don't consider it a game. It's clearly a game. The only overtly educational bit is the quote from Darwin at the beginning. I just liked it because it had good variety (at least at first), learning how to thrive as a spider vs. a fly and later humanoid. I'd like to see someone remake the game with a similar framework (i.e., emphasis on action), but greatly expand the number of species and types of mutations. Then again, part of the game's appeal is the ambiance, and it wouldn't make sense to try to duplicate that on modern machines.
