Over the years (yeah, I might be ol' guy in the forum), I have owned, or my sons have owned, the following:
Atari (yes, there really was one)
Commodore
Sega Master System (remember that one?)
Sega Master System II
Sega Genesis
Nintendo GameBoy
Sega CD
Sega GameGear
Sony Playstation
xBox
We've come along way!

Now my sons make their own money; I wish one would buy a PS2. If PS2 plays PS games, we should get rid of the PS and get the PS2. I wonder what it's worth?
We still have the Sega GameGear and Playstation, and the xBox. We gave away all the other Sega "stuff" about 3 or 4 months ago.
