I wonder why so many good games, who are about simulation and realism fail. Personaly I am an ex-counter-strike player, the game which I used to play for about 7 years but I wanted something more.
Games like Operation Flashpoint and Armed Assault and many others of this style who while they attract the intrest of the public don't manage to get enough attention in order to make a dedicated community which is going to play the game for years and thus make organizations that are going to host tournaments etc.

What do you thing is the reason? Is it because they are too complicated? Is it because they have not "official" maps or just beacuase the community is more "mature" and do not care about competitions?
