Mabye I should put my point of view into this discussion. It is not the usual part...
I am not a Windows or MacOS user, I am a Linux and Wine user. That means I play all my games for windows using wine. Well, even the bootcamp people do use wine, even if they do not directly see it. It is in the DirectX part.
Anyway, I did buy Sins, because it was advertised with having no copy protection. Note I siad "copy protection", not DRM. So I am one of these crank users who use strange arguments.. but in my case as a reason to actually buy the game. So when I did buy the game I expected a game you can most play on wine, because it does not use the most advanced DirectX features and has no protection system, that makes problems. What I did get was a game, that has even after 1.05 a memory whole, forcing me to restart the game all 5 minutes and a non working multiplayer option. A half finnished product. And not having copy protection was simply not true. Of course the stardock themself did not say that. I did buy the game right after the release here and that is something I will never do again. If I had waited a bit more, I would have seen the impulse program comming up, the multiplayer problems and other things.... because there was already a thread like that when the buisiness people here decided that 1.05 will be the last patch you can download without their program. What really annoyed me was to get a program that was months from being finnished.
So why not using Impuls? First simply because it does not work for me (problem with .Net). Frankly I don't care much about a 700mb download, I have this downloaded in less than 2h. And if that where an normal patch I could download it from multiple servers using the full bandwidth of my connection. And I would have to download the patch only once, because I archieve these things. The other reason I am not using Impulse is that it is a copy protection system of a bad kind. 15 yearsago we mostly had protection systems that required you to look something up in a book. Then there where systems, that required you to use a cd key to play online. Well, Impulse is of that kind, but worse. In that days you could still sell the game when you where bored, because it was only the key, not the combination of key and private data.
So for me sins might not have the cd based copy protection, but it is far from not having a copy protection. What it makes a digital right management system to me, is that you have to connect the key with private data, making it impossible for you to sell the game again.
But then again I said already I cannot use it anyway...
I am thinking strongly about putting my game on ebay, because I don't see that in the future the game will be more playable than it is already for me (thanks to impulse) and because the original reason I buyed the game for was just an illusion. But I won't stop here. I will tell people about how stardock interprets its bill of rights for gamers. And even though Sins is exactly the genre I like to play I will most probably never buy any stardock product again. I may download the software, if it was at last two years on the market and may buy it, if it works. If it is again a half finnished product without public updates I will delete it and not buy it. Done.
I am really also playing games that are over 15 years old and I very much know, that no game is supported for that long. So there will be a day in less than 10 years, where Impuls 23 won't provide the patches anymore. Ah yes.. there was also this nice move to sale a game that tells you it works on win2k and then the requiered update program will not work there. Would have annoyed me too, because my last windows box was a win2k box. So all of a sudden I would not even have the chance to play the game anymore, even if I would still use my windows box... and I made the switch from linux complete only early this year.
