I recently played an amazing DOS game where you have your country and you can declare war or peace with other ones, and i really enjoyed it. Growing up one of my favorite DOS games was Gobliiins 3, such cool memories!
Commander Keen: Episode 4 was the first game I remember vividly enough and there was always one bit I could never get past or figure out what to do next!
Loom and the other games written for that platform can now be run by the modern Scummvm, if you have the data files.
Gog.com currently has Loom on sale for $2.09. IIRC they have something rigged up to run it on modern systems, though I don't recall if it's Scummvm or some sort of DOS emulation environment.
