I admit, the GoVS isn't a bad one, it does sound like it is the government which you are president of, but sorry. My vote is still with GoDS, because let's face it, you have super powers, you're the president, and you have GIANT ROBOT MECHA. At this point the only thing left is to do a takedown move with it on another giant mecha. Then as the alien pilot is ejected leap out and surf his corpse shooting his buddies. Or something.
Seriously though, power creep. The Boss is badass always, but the level of power ramps up each game.. at this point the Boss is effectively a god. S'where my vote is.
