Assuming that your MMO gains enough momentum. Otherwise, the cost of setting up massive server infrastructure and distributed software, and hiring people to manage and moderate all of it, might well be more than you earn back every month.

Those odds are incredibly stacked against you:

- an MMO inherently requires a lot of the player's time, so the by-far most won't be playing more than one. Would they choose your game?

- network effects: players will usually flock to a game that has a lot of players already.

- people that know Elite are generally older with jobs, the target audience for MMOs are younger players with a lot of free time.

With EVE Online being the big elephant in this room, I doubt an Elite MMO will be much of a succes. Then again, feel free to prove me wrong, I'd probably sign up just for old times sake :)
