Now I realise the first thing someone is going to remind me of is that impulse is not an DRM at all. I'm quite aware of that, but it feels and acts just like one. And that I just can't stand.
I would agree with you if Impulse wasn't a value-added service, but it stays on my machine because it offers things that have nothing to do with DRM. For example, I can install the latest fully-patched SOASE in about a third of the time that it takes me to install it from CD.
But it's also worth mentioning that you only need Impulse to get the files, you can uninstall it and activate via e-mail if you really want to. Since Impulse doesn't control your access to the game (it can't revoke you), I'm not sure why it feels like a DRM platform.
I'm a firm believer in that the biggest reason why PC games are not selling as much as consoles these days is this whole bizarre DRM nonsense publishers keep coming up with that actually feels like punishment to customers that buy their products.
I feel stardock isn't nearly there yet, but I think the impulse requirement is a step in the direction of continuing this DRM death spiral that PC gaming is now known for.
I think the death spiral has very specific causes, namely: 1) Malware CD-checking software like SecuROM, and 2) The stupid assertion that a software license that is not perpetual is still somehow worth the same amount. I don't see Impulse as a move towards either of these ideas, so I don't think of it a step in the wrong direction (yet).
Now with this said, I have decided that for as long as I have to have impulse installed on my computer to patch sins of a solar empire I'm not going to buy any expansion packs nor any more stardock games. I know I'm only one person and probably won't make that big of impact on your books, but I hope others that feel the same way follow suit.
Hence lessoning PC sales even more... But really what other way can us consumers do to convince publishers to just stop the BS, and just let us patch up and play the game we bought?
If you really want to make a statement, pirate the game and mail the development studio a check for $100. That should get the publisher's attention.
