I've been playing on console, but I've recently discovered that I'm a lot better at playing with a mouse and keyboard as I learned with playing COD4 on my Mac. I've been thinking of purchasing Modern Warfare 2 for my Mac as well, but I'm wondering if the player base for the multiplayer on Mac is strong. Is it easy to get into Free-for-All or Team Deathmatch games? Has the game been hacked to bits? Is the game on Mac cross-platform with PCs? All help will be appreciated!
