A solid game both online and out but if you can just play for multiplayer.
By far the main reason you should by this game is for online play. Despite lag this is the cream of the game and where you should spend the majority of your time playing. There are two types of games: Conquest and CTF. Conquest is a game where you must capture enemy spawnpoints while protecting your own and not running out of "tickets". CTF is well capture the flag and return it to your side. Rank advancement is pretty easy except for medals. Medals can be pretty hard to obtain if your playing with experienced players and can keep newer guys from ranking up as fast as they should be but it adds to the enjoyment and addiction to online.
Overall BF:MC makes a great start for the series on the console. It offers a lot of potential in the future and is definately worth the money you will spend on it.
