First play here as well. I downloaded it from GOG in preparation for participating this month and started briefly for now to take a look. The GOG version is a bit confusing with a startup screen that lets you turn on background music, smoothing and high resolution portraits. It also has an annoying feature that doesn’t let you ALT-TAB out of the application so you are kind of stuck to the window until you exit, which it took me a while to find out how to do (save your game, get asked if you want to exit).
Now that I have purchased it, I might figure out a way to run it in a more standard DOSBox environment. Looking forward to giving the manual a once through and sitting down once I have a bit more time on the weekend.
I killed my first character by marching forward into a radioactive desert, ignoring warnings that I was getting very hot. I guess that didn’t come as a surprise.
