I know it's just a videogame, but it gave me a deep respect for helicopters, in a way that normal flight sims didn't give me for jet planes.
In the process, I've also learned a bit about the mechanics surrounding the drive train and the main rotor blade, and to this day I'm impressed by how it was made to work. You have a couple tons of metal, + fuel and people, hanging from the sky off a spinning rod with lots of tiny, rotating parts. The more I think about it, the more I realize I still don't have a good intuition for strength and wear-resistance of materials involved.
I wish I could fly one for real. Maybe in another life, when I'm someone with more time, money and risk tolerance. For now, I'll just wait for someone to build a nice VR simulator, and maybe my friend and I can resume our high-school competition in autorotating after simulated engine failure in bad weather.
