Pardon me, I didn't intend on insulting you or your Grandmother, but seriously, what you are proposing is pretty far fetched, but then so was landing on the moon (and please, no conspiracy theorists please...). I'm not a selective reader, I was just in a hurry to eat my dinner so didn't word my post adequately. I feel a little hostility in your answer (only a little) which is something you need to get on top of as you'll more than likely face a few more disbelievers in time that will ask you a few more questions than I.
I've actually taken some time to look up the game engine and its site and wonder if you would be planning to release commercially or as a free to all software package? Given that you will need to pay out an initial $1500 for the pro version of the engine, would you need to pay additional fees to release the game commercially using someone elses engine? I would expect so. Also, by taking on other developers, you would need to reward them financially too if there's to be a commercial release, and if it's not to be commercial, they are effectively working in their free time for nothing, which, going back to the example of the flight sims in my original post, causes people to join and jump ship at inopportune moments leaving unfinished work that someone new then has to pick up mid flow, decipher, and finish.
All I'm saying is that it all sounds to me like a pipedream, a fanciful vision of what you believe you can do and the first instant that someone questions your vision you go a bit rude. If me being skeptical makes you more determined to prove me wrong then good, it means I've had a positive influence on you and your ambition, I don't seek to belittle you or to question your or your associates abilities.
The fact of the matter is, I've seen this kind of thing promised many times, and each time I made a similar post which kind of received the same response. We have a saying here in the UK; 'The proof is in the pudding'. In all the threads like this I've responded to, not one of them has delivered a working title onto my hard drive and until they do, I will always respond with skepticism.
But hand on heart Hans, I hope you prove me wrong. Now there's a mission for you.
