How big is it? My bro's going to be getting the game for his b-day(he doesn't know shhh) and we're pretty short on save space(6450-something MB).I heard it's 7gbs that's not true right? How big is it exactly? It's impossible to look up this kinda thing,cause I guess no one gives a shit(small deal I know,just saying).This entails to the disc version. Thank you,whoever you'll be.
