I got most of the same systems and I got a system they don't have.. the vectrex. And yes my vectrex still works and I think it was a awesome "console" it has have it's own screen and speaker. Plus something the likes of astroid is pre programed into the machine.
You have a vecrtrex, but do you have a Game.com? 3DO? They're not THAT rare, but most people don't even really think about them/have heard of them.
I wanted a game.com when it came out but my dad wouldn't get me one. But really they sucked in the end but homebrew is going on with it I think. Plus DSL/cable would of killed it even if it was a success. Also the guy who owns all of that is missing Steel Battalion on the Xbox.
How does he fit all that stuff in his mom's basement?!
But seriously, nice collection. Super nerdy, but super awesome!
