to Strategy Informer last week, he mused that this was mainly due to the matter of "convenience".
"... honestly for me personally it's more of a convenience, because I can install it on my work computer, I can install it on my home computer, and with things like Steam Cloud you can transfer saves you know?"
This view is also shared by Lead Art Director Dorian Newcomb, who thinks that publisher-owned digital services only "make sense" for PC publishers:
"When you have a larger market that involves consoles, it doesn't make as much sense," he said.
"As a consumer, one of the things that I like about Steam which we are shipping out on, I like the fact that I can go there and get a lot of games. But for every service I have to sign up for, each one feels less appealing."
Civilization V was announced to be shipping with Steamworks back in May. When asked whether Steam should be this 'central service' by virtue of simply being first, Shafer said whilst nothing is perfect, Valve are in a really good position:
"I think it's a combination of being first, and going through the growing pains of improving the service. I think it's similar to how Blizzard have approached the MMO market - they are to the point where WoW is so polished, so big and so amazing it's hard to break into that because they've had the benefit of 6 years of time and 6 years of experience."
