If the game doesn't follow this criteria then I won't buy it;
A brand new engine. Use a third party one if you must like Cryengine or Frostbite (lolol in your dreams).
Campaign is 10 hours+ at least.
Campaign isn't filled with all that hollywood action garbage with snowmobile racing or dumb
plotlines like the
ing O.K Corral Firefight between British SF and rogue American troops.
Campaign returns to CoD's roots and provides authentic and narrated campaigns with levels being grounded in reality like CoD 1/2/3 ect and to a lesser extent, CoD 4.
Multiplayer gets rid of all the fluff like death streaks (wtf?) and accolades ect. Just simplify things. I don't want to have to customise like 20 different perks and loadouts before a game for 5 different classes.
