I notice in the OP that you focus only on Hitman. I used to have Hitman on PS3 but why do you limit yourself to only this one game? Will you not increase your exposure if you add many more games or make it game agnostic? Gaming is a big thing and a huge market if you exploit it smartly.
I don't see it that way, its main purpose is the online game store
They only started from the Hitman game because Dev is a fan of this game.
And for the future they certainly will not limit themselves only to Hitman games
