Titan line

The year is 3014 and for the last 200 years evolution has hit a stalemate. Wars have torn countries apart and treaties have united them. The world has be drained of nearly all natural resources and the 4 major nations left all control thier own large section of land and sea. They stockpile and hold what little remains close. The border have closed and now the 4 nations are at constant war fighting over what little resources remain. Tech has advanced into the largest combat ships the world has ever seen, mechanical mechs reign supreme. Aeronautical engineering is on the most cutting edge designs that are humanly possible. Each small conflict takes more and more effort to repel. You may chose to be a pilot, mechanic, a soldier, political figure, the choice is yours to decide what nation you choose and if you're going to go on the offensive or try to defend what you have left and wait out the others. Heck you may even fall in love through it all.
