I still plat C&C on my psone and many games on my ps2. Still turn on my WII and Xbox sometimes as well. My wife has an old atari 2600 and about 50 games that we play .
I guess thats about all except the DS and Philips CDI
Oh crap !!! Im a gamer 
I still keep my old PS2 around too. My PS3 doesn't play PS2 games, and I'm absolutely obsessed with the Ace Combat series! I've been able to play AC4, AC5, and AC0 and still have 5 and 0 (my brother sold AC4 to gamestop

Have to remember to buy another copy of that one), and I still go back and replay the missions over and over. I haven't been lucky enough to get the earlier AC games (and can't even find a place to buy them), or the newest AC6 since Xbox decided to keep it to itself

I've bought the AC5 and 0 soundtracks and play them all the time while flying AHII, and my first choice for a handle on AHII was going to be Cipher

It's really neat when you go back and place your old games and think "I remember this game being really hard" and then you blow through the levels.
