mine doesnt get played that much. when people come to visit, the kids usually want to play, and then after a while an adult or two will wander over and check it out if nobody is using it..i very rarely actually play it though. my 2 year old wants to play alot, but being 2, can't really do much other than mash buttons and then lose interest.
i really enjoy working on it, changing it, that kind of thing. lately it is making me angry because the monitor isn't functioning properly. sometimes when i turn it on, the monitor takes several minutes to power up, and when it does, it is just a garbled screen full of colored lines. the PC is booting just fine, you can hear it boot up and launch games. i often have to unplug it for a while to get it to work again. it sucks because i just about have the money i need to get a set of u360s and misc to redo the control panel, but now i dont know if i should do that, or get a new monitor instead.
i find that when i do play games on my cabinet, i play for 15 minutes or so, and then don't touch it for a while.
