I think the new Stardock service would be only programs made by Stardock or published by Stardock. I think they're trying to avoid being a big DD player this time round.
Yes thats the stated plan, but I'm pretty certain they never planned on selling impulse when they were starting it. I trusted Stardock to manage my digital purchases once and paid for it by having my library of games transferred to gamestop. Its not a mistake I will repeat, regardless of the stated intentions.
Lastly I really don't want to deal with a separate account and or digital download manager for each dev/publisher. Its bad enough I already have my digital purchases split between GoG, Gamersgate, D2D, and Impulse Gamestop.
Edit: Just want to add... if the only thing I had purchased via impulse were stardock products my view may be different. Since I could end my relationship with gamestop and just use stardocks new service. however since I have other games on gamestop i'm stuck in a contractually bound relationship with gamestop that I never wanted in order to access games which I paid for. Which leaves a bad taste in my mouth toward both gamestop and stardock in regards to digital downloads. Had stardock offered me a way to continue to access my previously purchased games without me being forced to deal with and accept gamestops contractual demands I would have taken it and we wouldn't be having this conversation.
I avoid steamworks games because they force a contract with a 3rd party service on me, and I view the gamestop situation in the same way. I was forced into a contract with a 3rd party which I didn't want in order to access things which I already paid for. They both leave the consumer with 2 choices.. accept the 3rd parties TOS or accept that the money spent on the games was wasted and give up access to the games which you paid for. Neither should be acceptable from a consumers point of view, and is not an acceptable way to treat people to me.
(really the only reason I even put up with DD is physical copies have become harder and harder to track down and obtain)
Edit 2: None of this is new, but since you either don't remember or never read my wall o' text type diatribes on the subject i figured I'd rehash.
