Icculus, the disc controller on the Intellivision was extremely comfortable and easy to control your characters with once you got used to it. The buttons on the side, however... yeah, your fingers would definitely be in for some serious pain after playing on the thing for a few hours heheh.
Cruxader, oh man, you missed out. The Intellivision was far superior to the Atari as far as I'm concerned. Much better game selection. Check out my reviews of "
White Water!" and "
Buzz Bombers" in the Shorts section of the site to see a couple of my favorite games on the system in more detail.
