Not an easy task to choose only 4... Well, let's see...Should be a lot more, but I'll stop on those and won't stress myself too much about it :D(click to show/hide)
Yeah that was tough.
As much as I love Intellivision Atari, and Colecovision I really kept it to the big major game changers that stand out in my memory.
If I had 4 more picks you would have gotten another Colecovision, Intellivision, Arcade, and Genesis game. I didn't even put a fighting game on my list. :cool
