TF 1942 was a helluva fun game, given the very limited system requirements. It was also the cause of one of the funniest experiences I've ever had on an airplane.
In the early 90's I was flying a lot to Singapore and used to play TF42 for HOURS on my notebook. To log on, you needed info from the manual, which was this very official-looking thing titled something like "Imperial Japanese Navy Intelligence Assessment" with "TOP SECRET" stamped in big black letters on the front. Anyway, over the Pacific I got up to take a leak and was standing in line in front of the lavatory when the stewardess comes up with a worried look on her face and whispers "Sir, you accidentally left this on your seat". She then produces the game manual from under a napkin that she'd wrapped it in and passes it over to me like it was the plans for Desert Storm.
She seemed pretty put out when I told her that it was just a computer game manual, that I was just a corporate lawyer and that the "Imperial Japanese Navy" hadn't been called "Imperial" or even "Navy" for nearly 50 years. Still raises a chuckle whever I think of it.
