I see your point and it is an excellent one.
Going by what you're saying then, Call of Duty 4 and Call of Duty World at War are two games I enjoyed the most out of the 30+ games I've had over the past 12 years. The Battlefield series is what really got me started playing as a team and making friends. So Battlefield, 2142, and Bad Company 2 are also cherish because those were the ones I had great friends playing with me, but without them the games would suck, and that's why Call of Duty is so great. You don't need to have any friends and you still enjoy the game a lot. I can't play Battlefield without friends. Not because I'm bad at it, but because it's just boring or something I can't quit pin down.
And above your tomb, the stars will belong to us.
