I also have soft spot in my heart for Rance Culzus and The Commander from Target Earth for the Genesis. This was the first game that left me in awe. Being a space nut, this game captivated me more than any other at the time. I have beaten it hundreds of times (literally) and in fact, I have beaten it a couple more times just a couple of weeks ago.
I am even devising plans of making my own homebrew PNP campaign based on that one game.
Gosh, how I *love* Target Earth
