I hope it makes a return, too. I had heard that Krome had shut down, so hopefully the delay has just been due to finding a new developer. I heard a rumor (from GDC, I think?) that Game Room isn't dead yet, so I hope this turns out to be true.
If it doesn't have any more updates, I could see why, though. $3-across-the-board pricing is kind of crazy. Some games are a steal at this price, but there's a lot of stuff that shouldn't have sold for more than a buck. And from what I've read at different places, Sunsetriders not being in update 013 really pissed a lot of people off.
