[Hitman]

True the hardcoded limitations prevented from converting it into a full range surface battle sim, but still if you used it for what it was designed - destroyer roles- you could have some fun with it. Unfortunately the AI was seriously poor, subs just went straight ahead without evading, making them easy to sink, and the enemy surface ships made it easy for you to cross the T and annihilate them. Multiplayer DD vs. DD combats were however incredibly fun, I think still worth playing nowadays.
