So upon buying and inserting the disc, Call of Duty downloaded with a huge HUGE 156gb update, then required me to download the MW2 launcher plus all its content. Am I able to get rid of the initial 200+gb Call of Duty game and keep the MW2 launcher and still be able to play MW2? Knowing activision, I’ll download this campaign pack and then have to download some OTHER dependency and I’m running out of space LOL
