At the time I wanted to get Hunt for Red October for the C64, but didn't play it until a few years ago on an emulator, so my view on it will be warped. But for me, my fave is the 1998 Rainbow 6. I've been playing computer games since the early 80s with my first console a Coleco Vision (not counting my Dad's pong machine), and PC gaming in the 90s is in my opinion the golden era of gaming. with the PC the best platform especially if you could afford a monster machine. Rainbow 6 was different from everything else on the market, so had it's own identity.
