I totally agree with the franchise going back to WW2 era but i'd like to see a modern day version of COD: UO.
Guns that take real skill to use. Tanks, jeeps, MG nests and anti tank positions. Levelling up inside a game. So once you had 1000 points you got more ammo, 2000 an extra grenade, all the way upto being able to call in artillery strikes via binoculars.
Damn the more i mention about this game i'm tempted to see if people still play! Just a shame it was only ever out on PC
