In my opinion, both Steam and Impulse sucks hard.
The only question is, which platform sucks more? And frankly that is Impulse by far. And even worse Stardock is pretending that they are the Jesus Christ and Mother Theresa of PC Games but they are doing exactly the same like other companies.
I just bought one $5 Game of Steam and thats it. Addiotional I own 2 Games that required a Steam registration (one of it just for Multiplayer). I will continue to refuse to use such platforms as steam/impulse.
And its really sad that I have to use torrent sites to get a game update.
And even worse is the non existing support of foreign language versions of Sins on Impulse that is somehow non existent. With every game update I´m somehow screwed as a guy that bought the german retail version. Of Course a Stardock guy will come along now and say that is is the fault of Kalypso but they say in their forums that this is you fault and so on.
That is a statement of a kalypso forum admin:
Wir können auch nur auf die Informationen zurückgreifen, die man uns zur Verfügung stellt.
Wir selber haben überhaupt keinen Einfluss auf die Entwicklung des Spiels oder den Erweiterungen und auch nicht auf Impulse, der Vertriebsplattform von Stardock - wir haben nicht einmal einen technischen Zugang zu dieser Plattform, können keine Passwörter ändern oder sonst etwas machen...
Translation: We only can revert to informations, that they(stardock) provide to us. We have absolutly no influence on the development of the game or it´s expansions and even less on impulse, the publishing platform of Stardock - we don´t even have technical acces to the platform and cen´t even change passwords or do anything else.
