To be honest I would say watch dogs is more impressive.
1. First game in the franchise.
2. Fastest selling new ip ever
3. PS4 version USA only has almost sold as much as MK8 WW.
Those three points say its more impressive to me. I could mention even more things but what would be the point?
Nobody's perfect. I aint nobody!!!
Killzone 2. its not a fps. it a FIRST PERSON WAR SIMULATOR!!!! ..The true PLAYSTATION 3 launch date and market dominations is SEP 1st
