Hmm, personally, I think it's a tad overrated. Sure, the video card is great, but the user-created level designs are usually pretty terrible... there's only a little pre-made content left, and more of that is getting overwritten every day. Plus, while there's a few intelligent players, most of the player base are jerkwads. Speaking of which, cheaters and griefers are MUCH more prevalent than the Gamespot review let on (hmm, Gamespot glossing over a game's less-fine points, no that doesn't sound familiar at all... ^_^

.
Plus, the grind in this game is what biases me against the grind in most other MMOs... I think "this grind feels a little too close to
Real Life to me" and it puts me off... very traumatic. Earning money is really tedious as well. However, cheating isn't that difficult, and in the player-nation I'm in (some weird place called "the USA"), cheating is actually rewarded pretty heavily in this economic substructure. So that's negative points, even though it's easier than in most games.
Plus, I always hate games that bill themselves as free, but tack on a lot of hidden charges.
Still, some of the minigames are fun. But overall, I don't know if it's worth it. Seems like a lot of advertising over a mundane experience, to me.
