You can find Wasteland on abandon ware sites. Not that it translate well 20+ years later.
For me it was the first game where I was all in. I had played bard's tale, wizardry, Might and Magic. I knew the fantasy schtick.
Then I played Wasteland. It was gritty. It was dirty. Not dirty as in swearing (it had that too) but it wasn't fantasy. It was post apocalypse. Burned out towns. Raiders. Bums. Gambling. Weird stuff to do. I got wasteland herpes for a three legged hooker. It was smart, funny and edgy for its time.
Did you play Fallout 1 or Fallout 2? Fallout 1 had similar elements and felt like a reboot or retooling Wasteland.
