What I have found is unless you have the power of millions of dollars behind you, and I am talking on the scale of Blizzard, EA, Sony Online Entertainment, you wont see a project this big get completed, and if it is it wont be done well.
Lets look at games that have anything on the scale of Mechwarrior Online. Which is looking to have a world conquest system and factions, not one but 5+ and over 20+ different mechs to use.
-Planetside1 or 2, are on that scale but have 3 factions, huge maps, and several vehicles and weapons. But has the backing of SOE and cost in the lines of MILLIONS of USD, and has a programming team that is in the dozens.
-WWII Online, By Cornered Rats Studios, they had Strategy First as their backer, and they pulled out during beta, forcing the game out early. CRS had plans on a massive WWII game set in northern France in May of 1940. They on launch 12 years ago had maybe a dozen vehicles and 3 infantry types. The game had and still has quite a few bugs, and is being kept running by shear force of will by CRS.
-MPBT:3025 by EA Online, HUGE idea for the time, had dozens of programmers, and a huge chunk of money thrown at it. EA killed it because it wouldnt be profitable for the cost they were putting into it. (Which many of use thought was Bullsh...)
Thats just three games that are along the same lines as MWO, each with different levels of funding and commitment by the developers.
As you can see unless you have had millions of dollars thrown at it with team of dozens if not hundreds of programmers its just not going to happen.
