Lets be honest here: 9 months ago this seemed like a great game with a huge player base, it was active, it was shining. Surely, there were some clouds in the distance, some of us could tell whats going to happen if nothing was done, but most of us quit the game months ago.
Now I come back half a year later and see a ruin in place of Babylon.
So, what do you think has killed Spiral Knights?
-edit-
to be clear: I am not saying SK is dead and buried (that'd be exaggeration). I'm saying the game looks like it shrinked down significantly with less active players and far, far less trading going on.
The answer is:
> CE price is too high.
Everyone lose their hope and give up. Then they quit SK.
