It's not a DOS game, but it's still as old as many, so here works anyhow.
But yeah, I just got Starcraft and began trying it out. I'm liking what I've done so far. I've been playing it using a shell so I can have it windowed, then I'm using different screen resolutions to change the size of the window.
Since I have dual monitors, that's the best way to have a movie or TV ep playing on one monitor, full-screen, while having a game going full- or near-full-screen on the other monitor.
It's good times. =)
