COD 5 was really great game, at first i preferred cod 4 but cod 5 slowly grew on me.
It was nice to have your own server (no global ranking BS) 48 players max, changed the settings how you wanted.
MW2 no dedicated server and 18 players and same crap with the others with a TON of restriction. In my opinion, I wish we could all boycott their junk (toward PC gamers) but that's not obviously gonna happen.
