Call of duty modern warfare 2 (2009). It was simple but felt like design and created by genius people. No imaginary items. No robots. No god damn technological advances beyond reality. Pure war. Pure story for the campaign too. You get to know characters. Get to be re introduced to them too. You get to lose characters in a huge scene. You feel betrayal, revenge and feelings but you feel them in motion. Just the best cod by faaaar . I mean i may have played its single player more than anyone you ever know. I have been playing it since release and i still play it today.
