Starscape? Holy shit, I played a demo of that years ago! (Before I gave SC2:UQM a chance, even!) I wasn't in the position to register games like that with ease, though.
For ten bucks, I'm somewhat tempted...but I was really hoping for half of that (five dollars), which would make it an impulse buy.
(I'm only this stingy due to an extremely shoestring income...)

I just paid $2.50 for 2 Indiana Jones Games, Loom, and The Dig.
Sorry that was D2D not Impulse. My Bad - forgot where I was for a minute.
