Okay okay okay. Can someone explain how this is going to work if I buy the game through GMG? Like, am I actually going to have to install a new client or will I just be able to load it up through Steam?
Yeah, just register the key GMG gives you in an e-mail the day of the game's release and plug that into Steam.
GMG does have their own client called Capsule, but you just don't need that for Steam-required games.
You'll need Capsule for any Non-Steam games you buy from them, though.
When dealing w/ Steam-required games from other places [Gamersgate, GMG, D2D, Impulse, Amazon, etc] you take the game-key you are given by the digital distributor, hop onto Steam, and register it onto Steam.
Then, you can let Steam do everything from there forward.
I'll copy and paste part of the e-mail I got from them about my order w/ DE: HR.
These are the specifics.
