Here's something very very old I found in my old files on my older computer. It's a Dos clone of Dungeon Keeper called Space Station Keeper. The game is nowhere to be found today and the website of the author is in the Internet archives.
The game is only in alpha stage and has never grown up, but it offers 7levels, plenty of creatures, some different spells and rooms.
So, here's the game, but it's far from being a very beautiful game. At least, it tries to work correctly.
You'll need csdpmi5b in order to make the game to work. The game works under Dosbox perfectly but you'll have to slow down the game by lowering the cycles and making the core simple.
