Same here. I am having a great time with the game. Last sub sim I had was Aces of the Deep!
This is a long way from the original Silent Hunter from SSI. I remember it took me days to get it installed and running on my mightly 386sx computer, lol.
Yeah it has some bugs, but they are not game killers for me. I'm on my 3rd patrol and just got spotted by the escorts of a convoy I was going to attack. They kept me down for a good three hours. great stuff!
