So, I think I should make a new game engine, and hope that (with Dw's help) it turns out to be okay...

Main ideas:
Halo Based Space shooter containing all ships from Halo universe...
A galaxy that can old the following list of planets (at minimum):

UNSC Colonies
Covenant Worlds
Covenant Homeworlds

An advanced combat, trading, diplomatic, imperial sistem...
A expansive campaign mission with consequences of the outcome (in case of sucess you go to one, in case of defeat, you go to other...)
Capacity of landing in planets and participate at land battles/ missions...

More to be added...
