bansama: While Elemental may be interesting, I know I won't be buying it until it's being sold for around $5 to $10 and that's simply because it's only going to be available via Impluse here. The game itself may well be worth far more in terms of enjoyment and all that, but being tied to Impluse devalues it significantly in my book.
Since installing Win 7, I've reinstalled a number of Steam based games and GamersGate bought games, a few D2D bought games, a couple of GOG bought games and a couple Big Fish bought games. I still haven't reinstalled a single Impluse bought game. I just can't be arsed.
I think Impulse isn't needed to run any games downloaded from it, including Stardock games.
Anamon: I know Steam does it too. But it is really a rare exception there, which makes a big difference. I don't think it is purely a publisher's decision if the same games are usually available to me on Steam, but not on Impulse.
Coelocanth: While I completely agree about Impulse needing to get worldwide availability for their games, and Brad needing to stop his constant whining, I can actually see this being a publisher decision. Seems counter-intuitive, but it could very well be the case that there's an exclusivity agreement with another distributor (such as Steam) for other countries/regions and Impulse isn't allowed to sell in those areas. Likely this is not true in all cases, but it (or something along those lines) certainly could be for many.
That was mentioned too on the impulse community forum, but most games are available on steam, gamersgate, d2d, and such, except for Impulse. Did all those download services sign an exclusivity agreement to keep Impulse out?
