this subsim is the king of sub simulation! worth every bit of the price
well first i buy this game and install but its in Czech language. then i re-buy it and install, this time it worked fine (phew). the graphic is amazing, but SH4 had a lots of bugs, controls are hard and no tutorial too but you'll get used to it though, after hours of playing game. and i'm sure there will be a patch sometimes, so don't play for a hour, feel unsatisfied, and say that this game is a piece of crap! it's a masterpiece and the expansion pack is cool (i buy the uboat expansion too). with more than 30+ types of ships, single-player & multiplayer fun and challenging mission, awesome graphics, and improved user interface, you won't get disappointed by buying this! it's really worth every bit of the price, so grab your wallet and spend some bucks for this awesome game
