I hope I'm not the only one who thinks this. But if the correct licenses and permissions were granted, wouldn't this game be able to have other cool stuff besides guns in it like mechs (stuff from gundam and other series), stuff from other video games like Portal and Half-Life and Crysis, tanks, computers and gadgets.
I can't be the only one who thinks stuff like this would be good additions but it's probably impossible because of licenses and permissions.
But if any of these things were possible, what would you guys want to see in this game the most?
