Don't get me wrong. I still can appreciate a game for what it was and is now. Still, there are times you can just pop in an outdated game and get the mood you get at times like: OK, time to play something newer-ish or something. It is like that Tool song Stinkfist, "It's not enough, I need more. Nothing seems to satiesfy. I don't want it, I just need it. To breath, to feel to know that I am alive." A little exagerating, but a nice metaphor. I still play my NES and everything, but it seems like you have to try harder to play it at times. You just tend to enjoy the games a hell of a lot more when you play them when they came out.
I didn't get into video games until the NES and Master system era around 86-87, so that may have to do with why I never play atari and other oldest school systems. I did always like the 1st person view tank combat game on atari that I played at my friends house when I was 5.
