I scraped up some room on my HD (for my first HD), bought the Shadowgrounds Pack (Shadowgrounds + SG: Survivor) from Impulse to download today (which goes for $24.99) -- and used that Survey-2008 code. It was like $18.71, after the code was used.
Took me about an hour to download each of them a piece. Looks like Steam's got a major competitor here -- no DRM at all, no forced DL's on you for updates, no forced program to boot the game up, etc etc. Very happy w/ Impulse client here. Easy as pie. I'm sure in the future, I'll be buying some stuff from Impulse.
Though, there's no real installer file to DL. Basically, you are told to just back-up your folder where the game's at -- which is fine and all.
Been playing some Shadowgrounds (Original). Goddamn, now I know why I liked the demo quite a bit ago, when I tested the demo. Awesome action and controls. And, I like that I can upgrade my weapons and all.
I'm on the 2nd level, playing on Medium. Almost had that boss, but it got me.
