In terms of evolution. Think about it, the transitional leap from CoD4 to MW2 was far more distinct than MW2 to MW3. In fact, I like to consider 2011s entry as “MW2.5”. The game just felt too much like an expansion pack to be deemed as a true sequel imo.
On the other hand, the 10 year gap between MW2 and MW19 felt way more pivotal in the sense of graphical improvement and overall production value. What do you think?
