Yeah i'll try using the bigger characters. I'm a light weight kinda-guy (koopa,toad).
It's over-rated, and the PS3 graphics are along the lines of Saints Row 2 quality. Dull textures, car physics are extremely arcade-y, guns can't be fired while you're driving. The idea is new, and it's fun for the first few hours. But every story mission, side mission and collectable is the same. Sneak in, hack, escape.
It will be interesting to see what they do with the Wii U version. They've already delayed it, saying they're going to make it the best version possible, and hopefully the graphics are better then the last gen versions.
