There's certainly a difference between letting a dev know that you would think his game could be better by changing certain aspects, or even asking for additional content or an ending OR FORCING A DEV TO DO SOMETHING.
I'm all for creative vision, but let's also not place these people on too high a throne.
After all, many games are in the end just a product for us too enjoy and if that's the goal, accepting input from those you expect and/ or want to pay and play seems only natural.
Nothing screams swollen ego more to me than devs who actively snub their fans and cry artistic licence, when in reality they fucked up but are too stubborn to concede that.
That's not aimed at likesblondes btw, but we certainly know this type of devs both here and in more professional games.
Yes, I was one of those who certainly did NOT think the way Bioware handled the whole mess surrounding Mass Effect 3 and it's ending was the right way to go about it and I never like it when any writer thinks his "artistic vision" takes precedence before considering the story so far, the way the characters have acted until now or the complete tone and direction of a game or comic.
Other examples for this type of behaviour apart from Mac Walters at Bioware would fe. be the comicbook writer Brian Michael Bendis and many, many writers for television.
Also, as for sarcasm on this forum, IDK but I been told I handle that quite well.
Now, that was sarcasm.... or was it.
