do you see what happens to all the microsoft Combat sims? they get modded and modded, and it won't take long until some dumba$$ builds himself a plane able to carry 2048 missiles and about 500guns, going mach 5 and turning on a post stamp......where's the fun and realism in THAT? ED is doing well in not releasing their SDK, Lockon stays the best this way, if they give us the options to design planes and flight models, but keep the tools to import them into the game, and only let tested planes which are no cheats enter the game, it would be ok
