I guess the argument with Mass Effect is that games are an entirely different medium, and games that encourage role playing and intense user participation can be expected to evoke a different response than, say, movies.

Okay... sorry, that's just what Winterclaw is saying. I agree.

It's one thing not to like the ending to a Harry Potter book, a variety of entertainment that, even if I had read the entire series, would only have involved me for 15-20 hours or so.  But a game that I might play for 300 hours represents a significant investment of my time and likely my emotions. 

The same could be said, and was said in the original article linked by the OP, about long standing comic series with which readers had engaged for years.

So in the end the finished product belongs to the creators and they should and do call the shots.  But in some media particular, failure to take into account the emotional investment of spectator-participants may result in backlash.

As for Poser content, I think vendors are working for a very slim margin and deserve  considerable gratitude for producing anything beyond erotic slutwear (or whatever it is that actually sells in larger numbers).
