Falcon BMS is one of the best simulator experience I ever had. There is an awful lot to learn to be proficient (training manual is 400 pages) and there is many more pdfs explaining mechanics of the game, but trust me, its worth it. This sim increased my interest and knowledge in aviation a lot!

Can you see my hours played? Yeah, I can recommend that this sim is worth your time.

One more thing, don't try playing it without throttle and stick. Even the cheapest setup like Thrustmaster T16000 will enhance gameplay like x1000 times.
