It started out rocky but over a year on its now in its second generation (MAG V2.04 at the time of writing) and with two pay-for expansion packs out at GBP 8.00 ea it covers multi-player games from twelve-a-side to thirty two-a-side three way to a massive sixty four-a-side battle with a huge amount of battle gear.
With one character slot by default and the option of two subscriber slots to expand your experience you take control, this game is a must-have in your library if only because the massive amount of players means you will always get a good game no matter the time of day or year.
Only consider reviews of the game since August 2010 because it has changed so much since release (Until of course they go to MAG 3.0), at GBP 25.00 its a little pricey but if you want to guarantee disc quality its worth it, never pay more than GBP 15.00 for a pre-owned verison.
See you on this digital battlefield :)
