The current Market Conditions make it extremely difficult for a new start up to gain a footing, I beleive this was the fate of Skill Rush. They had a great concept and the game itself, spades, is wildly popular.
Unfortunately most people have less disposable income right now and are concerned about their local economies. That coupled with banking difficulties was apparently enough to push this company over the brink.
In the long run skill games will flourish and prove themselves to be a profitable sector for affiliates, we just have to gut it out and help develop that vertical so we have more options for our players.
