Lots of people still must be playing their PS2's even though the next gens have been out for quite a while now. But you know a system is dead when they do not make a Madden for it anymore.
I haven't played my PS2 in years. I know it still works. My collection of games is in good condition as well. I'd play it more if I hadn't already beaten literally every game I own for it. But if I ever decide to fish around amazon and ebay for more games for it, of course I'd play it. Unfortunately, many of those games are rare and fairly expensive now with them being out of production and all.
