Yeah, no. My Steam fanboyism is being unleashed on this topic, but I'm still thinking logical. If you don't know what I'm talking about, then read this here article:

Basically GamersGate, another digital copy distributor, thinks that they can beat Steam in sales. Hmmm, how many companies have said that and failed? Oh yeah, all other digital distributors.
I especially love this quote here; "many gamers out there don't like Steam and see GamersGate as a better alternative." There is no proof of that and therefore is opinionated.
Honestly, I don't think this will beat Steam, Steam has been growing strong and has many increases in sales throughout it's time. If GamersGate does beat Steam, it won't be for a long time I assume.
If Gamersgate wants to beat Steam, they will need to find a way to make their DRM less intrusive than Steam. As of now, most people forget Steam is even a DRM software because of all the features Steam give them. Not to mention it works really well. With Steam offering a new screenshot system, and video recording probably coming later as a next step, Gamersgate is going to have a lot of catching up to do.
