Excellent. I understand this. big picture mode is a treehouse where it could be a castle by now, and the rest.
And I hate to undermine this whole post like this,. I'm not trying to be curt are evasive, but my argument is going to come at this somewhat sideways.
I don't see any other comparable platforms doing significantly more than this as far as activities that improve the platform. Perhaps even none as much as this.
Valve may let some of the features develop slowly or even break, (I've experienced a problem with steam OS wherr a bug broke it after 3 years of problem free use. Presumably because they left a bug hang in there as they moved onto steamos 3.) but just the fact that they're doing this stuff at all I think puts them head and shoulders above even a stellar store like gog... When it come specifically to 'doing something'. Or, reinvesting in the platform to better it.
So that's my argument. I don't see anyone else doing much more than these activities. I think the fact that many are sort of rickety is balanced by the fact that these things exist at all because nobody else is doing them or at least a comprable number of them.
Edit: VVVV hey
