GTA 5's recent debut trailer has been remade, shot-for-shot in GTA 4's Liberty City, so we put the two side-by-side to compare how much Rockstar's GTA technology has evolved. The trailer has also been remade in Minecraft and compared to the original San Andreas, but the GTA 4 take, credited to 'Bean' according to a subtle on-screen graphic is something else. Check out the comparison above to see if Rockstar is breaking new ground in the open world genre, or if we've seen it all before.
