i see lots of eve similarities. sorry, i'm not looking to contribute, but perhaps it would be helpful for you to look at eve online (which by the looks of things i'm guessing you've already done) and think to yourself: realistically, will this make money?
it's a great start, and a great idea for a hobby game, but don't expect to make money out of a space game that looks just like a well-established and successful mmo. hopefully you'll have more up your sleeve than re-inventing eve (rhymes).
