You read my mind LOMAC have big "cost", and in main - for it's potential, tecnical and (priority) person's (developer's).

But not only for it's potential - it's even now is a great simulator, which only (in modern time sims case) it have such combination of "feel of flight" and hardcore avionics (not always correct, but realy hardcore).

PS
Sorry for my english vodka in blood, you know...
