PC has dedicated and private servers. So unlike console, there can be untarnished lobbies if people are still playing the game.
Does anyone here know (not speculate) if there is any population of people playing those games?
I played CoD:MW2 last year sometime in the summer and there were some decent servers, but most were like you said hacked and what not.
BF4 is a better alternative if you’re looking for something like that. I always find good servers when I want to play that.
