.... I was vehemently against it. That changed quick once I starting using it.
Exactly the same reaction to Steam. Initially against it, but came to realise that was a knee-jerk reaction on my part, and I was wrong.
I can see the limitations for anyone who wants to modify the game in particular ways etc etc, and its certainly true that some aspects of Steam don't give total freedom in that regard. However for the overwhelming majority of people that's not an issue. Steam will never be all things to all people, cant happen, but pitched at the vast majority of those who play Games as it is, it works, and meets the need of that group well.
Its a commercial enterprise, its not going to cater for minority groups - pretty much by definition - and I doubt that will change, certainly not in the near term.
Maybe in a Commercial sense, once it has nailed the commercial "low hanging fruit" - they will focus more on the more niche groups of whatever nature. Its a commercial Enterprise, they will go for maximum return they can for what they have invested. I cant see that changing what they do for a while yet, certainly not until they have finished moving into areas that give a better return on Capital invested.
The latter is reality. I don't necessarily agree with it, but it is the real world however much we would like it to be otherwise. I can see this easing somewhat in a few years time when they are forced to move into other areas to increase - or at the very least maintain - revenue Streams. Maybe then the more High End Gamer needs will be met, but its not going to be before then - that's Commercial reality.
Even Sid "sold out" to Steam ..... its todays Commercial reality, like it, love it or hate it .... it will be some time before it changes as such..
