i have played all those games when i was in my dorm, and like i said, i rebooted once a week at the MOST, i played at least 2 of those games listed for at least 30 minutes each, each day, besides, some of the C++ compiling i was doing for classes taxed my system much more than any 3d shoot em up ever could. and when i was gone, my computer was always being used by my roomates, one of which was into architecture (lots of CAD, LOTS of memory) and the other, well he was just into porn, but the PC was always working, and i probably actually NEEDED to reboot about once a month due to it getting sluggish or windows crashing
