I can't believe that Intellivison isn't a part of this poll!! I'm glad Lilred mentioned it, because I was starting to think I was too old to play in this thread.

I have to go with Sega. I missed my junior year of college playing Shadowrun on Sega (don't worry... I made up the classes the next year )
I briefly considered Nintendo . . . I was unstoppable at TechmoBowl and Super Contra . . . but I had to go with Sega in the end. Nintendo's D-pad had those sharp corners that would leave a blister on my thumb and force me to go on the disabled list in the middle of our Techmo season.

I'd tend to agree with Arsenal, though. If I played it in college, it's not an "old" system to me. That pretty much narrows it down to Atari, Intellivision, and Colecovision. Oh, and Pong . . . but I'm not quite that old.

Can I write in Intellivision?
