Its not because I disapprove of GTA that I made my choice. Its because of that disapproval I have never played the game so I have no idea what he could do. Thus without that knowledge I vote for the other guy.
I still say Shepard has got that one. With tech and biotic explosions, modded ammo, uber powerful biotics (can create singularities come on) plus weapons of mass destruction (Cain anybody?). Shepard has it in the bag.
