I personally enjoyed SH3 out of the box. However i was very very annoyed AI wolfpacks weren't included. If you were in a Type VII from 1940-43 the wolfpack was whole basis of the Kreigsmarines strategy. To leave it out was such a sore one!!! However we were advised due to the problems of making AI routines etc and within the timescale it was not possible.
However this will be 5 years down the line and technologies have changed and i hope it makes it this time as to leave it out would be a travesty. They can ramp up the graphics all they want but a U-Boat sim without U-Boats in the same grid zone again would not impress me. However i'll still buy it on day one.
