If Desura is a place for people to do exactly the same stuff as on steam but when steam doesn't accept them or whatever.....then it IS steam! Not in name, but in concept and in mind, yes it is one service in our minds.
Not in my mind, and I suspect the minds of many others. Steam isn't the only distribution platform out there. The two share similarities in execution, but Steam and Desura have two very different focuses in my opinion; steam is targeted at average gamers, who like to play big budget games as well as some well-known indies, and Desura is targeted pretty exclusively at indie gamers. Desura is also a lot more open than Steam which means you have to sift through slightly more crap to find the good stuff, but is still a good policy in my opinion.
I do agree their customer service is pretty bad though. Might be due to the team size, but Desura is all over the map when it comes to approving game updates, news, responding to support contacts, etc.
anyways stuff is crazy since LoL is as big as Steam itself, and I'm happy Paranautical Activity is on Steam and not Origin!
I'm not sure why you would be happy that the game isn't available on a particular platform. How would that negatively impact you in any way?
