I have a harder time getting really into any of the older systems I never played when younger. It must be a nostalgia thing. I don't think anything could ever displace the 2600 as most played system. I have a lot of systems I don't play, although part of that is just not having the room to set them all up right now. In the last year I've gotten an Intellivision and Colecovision, but not played either very much. The Coleco is great, the Intellivision...I want to like it, but the controllers just ruin if for me. I have lots of good games on other systems that have controllers with a normal interface. When gaming time is limited it's hard give the Inty a fair shake.
For me, if it's not hooked up I'm probably not going to dig it out to play it. One day, one day....(the plaintive mantra of many a space-deprived classic gamer) I will have them all set up in one giant entertainment center of doom. And it will be glorious! That was supposed to happen this summer, but given the recent torrential downpour and the condition of my basement it's not looking good. I have the tools, the plans are already drawn up, maybe in our next house. One day, one day......
