It's not like MA2. Not even close. There's classes....but it's like TPS + poor excuse for a game story + magic= Shadowrun. I played it for a while, and it was fun, but nothing I could continue to play for more than a couple months.
And while on the topic, realisticaly there's not a comparable game to MA. It's just that simple. You have a few TPS, a ton of FPS(few of which are good), and a ragtag bunch of driving, RPGs, and other random games. Comparing any game to MA is laughable.. There are few games that have had the longevity of a competitve community that MA had. It's due to several reasons, mostly that there are many more choices of games. Back then...the best team based game was MA. And it was for quite some time.
I personally enjoy COD, even though I wasn't much of an FPS player. I like the multiplayer options, and the earning of weapons/perks/ranks makes the game slightly less stale.
