Have you seen any other map in the Map Development ?
Some of them sure sounds promising, but hey, the more promising it is, the pressure you will be, trust me.
But if you think at the positive side, it would be amazing if we get the chance to finish the "epic" map we created like 4 months.
Also, I think you need a team, that will keep you motivated because if you work alone, you have no one to discuss with, and if you have problem, you can't share it with the teams to further inspect the said problems with the map, get a team !
