Quitefrankly;
This game/simulation is all about patience and manoeuvering stealthily in for the kill as opposed to jumping right into the action (although the single missions do that). Yes, the missions are fairly repetitive but for the U-boats and Pacific Sub drivers that was the reality ("go to Area X, patrol, sink enemy ships, come back home, rest, refit, go out and do it all over again"). The bonus for us is we can do in hours in the game what it took months to do in reality.
Don't forget it's a historical sim and the object is to sink enemy ships. I'm not sure what you mean by wanting it to "be more of a game".
