Is crap. Not even gonna link to it.
The biggest problem for me is that the visuals were so murky I couldn't tell the monsters from the trees. I walked past monsters and did not see them. (If you've played Diablo 2, you know that section with the tiny blowgun dudes? Same problem.)
To even run it you had to download an extra NCsoft client of some sort and I'm not sure what the point of that was except probably to try to sell you more stuff. Especially since Dungeon Runners is 'free' (but has constant rainbow sparkles yelling 'PAY FOR ME!' all the time)
Also, it thought it was funny. It was not. Almost anyone who claims to be witty and tongue-in-cheek about parodying the cliches of the genre is full of fail, it's almost always heavy-handed and crass, and rubbing our nose in 'Hey, this is that stupid thing all games like this do!' makes it more noticeable and more annoying, not less.
Anyway, if you want a proper review of the thing, try here instead - I uninstalled it already.
If you want to play a fun light-hearted dungeon romp in the Diablo vein, play Fate instead. It's still dumb but it'll keep you happy longer. At least, it did for me.
