Digitally? Or physically from a store where you had to do the literal walk of shame back to your vehicle?
Joking aside, is it because of some perception reason like you're a casual dudebro and you didn't want to be associated with that or you just felt legitimately like the games were too similar and not worth buying just for new maps?
If you like those games, fuck it, embrace it, buy it and enjoy the hell out of it. It's always been one of those things where I'm a huge fucking gamer, but I always distanced myself from multiplayer and I hate FPS and more specifically military based FPS. I can only tolerate old west games as a FPS for some reason.
