Aces of the Deep. It remains the best realisation of what we, perhaps inaccurately, call a dynamic campaign I've still ever played. On top of that there were a whole bunch of features that leave the modern and far more technically advanced sub sims like the recent Silent Hunter games standing. Best damage management ever, for a start; working wolf packs; 'Be More Agressive!' smile

I remember getting hit bad by escorts and sitting in the mud for 18 hours at the bottom of the St. George channel hoping that my crew could get the pumps working again. our scope and sonar had been destroyed, torpedo tubes were leaking and I thought it was all over. We fixed the pumps and got rid of as much flooding as we could and then, with the oxygen running out and CO2 building up, and without any idea what awaited for us above, I gave the order to blow the tanks one last time...and against all out fears up we went into a still, quiet, moonlit night. Superb.
