Yep, yep, yep. I am the proud owner of an Odyssey2 that reaks of urine and god knows what else I bought at a Salvation Army once, and about 15 horrible, horrible games for it. Oh, how I loathe that system.
I also have a Vectrex, Colecovision, Atari (all three) and Intellivision. The main one I want is the original Odyssey, all the others are terrible in my opinion. The games are ridiculously cheap (like, pennies) and you can buy hundreds at a time at flea markets and the like. There's nothing like doubling your game collection by spending 20 bucks! Of course, I'd rather play Grand Theft Auto: Vice City than E.T. or witness the racist porno escapades of General Custer, but hey, I'm a completist.
