I have played ghost on pc and xbox and belive me the pc version is much better both in terms of hackers and game play .Although there are wall / aimboters on the pc version the xbox is inundated with them first time I played tdm on the xbox I prestiged because of a hacked host and would often come across them in at least 25% of the games where as the pc was about 10% ish at best . And the graphics and speed of the xbox were crap even when compared to playing on a low end lap top never mind a desk top pc .The only saveing grace for the x box is because they are all the same specs more or less the lag compensation problems are no where near as bad as the pc .
Well mayb they should componsate xbox players as well. There was a time when they would (make it up to you).
Anyway xbox may have cheaters and modded servers but there is still a huge player base which is a "good reason" to buy the game and dlc's. For PC, I really don't see the reason in spending extra money for a game with a community of a few thousand players worldwide.
The dlc comes with 5 maps for the multiplayer community that has at "best" under 5k players worldwide.
xbox has how many players to play those maps with? way more than 5k. For xbox it's worth the buy. PC isn't.
