The PS3 had many open world games expecially later in the generation and some of them looked really amazing for the hardware. But which one do you think was the most impressive? Infamous 2 for me. The game had the graphical quality of Uncharted 2 which was one of the best looking PS3 games but it was an open world game and it had amazing special effects, destructible environments and huge enemies as well as tons of enemies on screen.
