On the scotsman website,GTA 5 is said to be 49 square miles. 50 if you average it out. Bacally it's 50 square miles. I don't know how big GTA 4, Red Dead Redemption, la noire, and SA are, but i know that's a huge map! If someone knows the map size by square mile for GTA 4, RDR, LA NOIRE, and SA, can you put them in a post so people have something to compare 50 square miles to. Anyway, GTA 5 is 50 square miles and the budget is said to be 170+ million.
