The middle part there, about 'not cultured', is probably what will get you the most shit, especially here on GAF, since the audience for the XB1 on here is probably a fanbase that is more diverse than the larger buying audience for the system at large, you know?
A lot of folks on here talk about games last generation fondly, that did terribly in the wider buying numbers, which means that they're representation of the potential audience buying those kinds of games. I mean, people on GAF are really excited for Scalebound, but I've heard practically nothing, ever, from customers regarding that game. Maybe that will change a bit after Gamescom, but I don't expect that to be the case.
That's why I make the commends I do on here. That GAF has a lot of people that are more deeply steeped in what the various systems have to offer, and as such, are apart from the larger trends shown in the gaming communities.
As to how MS have contributed to the gaming market, I don't really want to comment on that aspect. I think they've lead to some great games/franchises coming about, like the origins of Mass Effect, which I loved (When I finally played the trilogy on PS3, haha). At the same time, some of their focuses/pushes and methodology I do feel have had negative impacts. I don't think Sony is blemish free in that regard either. And Nintendo is so backwards on so many things that it is very frustrating there too.
I feel Sony has shown the most growth of the three companies in terms of addressing what needed to be addressed to be more of a positive influence for console gaming, but none of them are perfect.
