Anyone discovered this little thing yet?

It's a mix of Runescape (ugh, i know) and WoW.
You got a ton of achievements to earn, professions to train, etc. Graphically it's better than runescape obviously, and this plays in the browser (java) as well.
It's not horribly bad, and the game is getting updated frequently.
(oh, and it's free obviously)

The biggest issue i got with it so far is the weird camera controls ASDW, which seems to be inverted.
That'll be editable later though.

Inventory space will be an issue probably, but you can expand that - its a free game, you can't hope for too much in that regard, but perhaps it'll improve later.
