I'm getting the impression that what you're saying boils down to: if I cannot make a build, then it is not roleplaying. So roleplaying is fundamentally about building a character. I disagree. That's what roleplaying games may be about, for some people. But thats not a prerequisite to playing a role in your own way - which is what constitutes roleplaying itself. If I am playing a farm boy[predetermined], who is to fetch a bucket of water, and there are multiple ways of doing that(within physical boundaries of being a boy), and I can express the values, attitudes or mental states of my character in some way, then that's roleplaying regardless of whether I were given an opportunity to create a build. This might be a semantic problem, if you consider "roleplaying" to be an act of playing a roleplaying game(which has to include more than roleplaying itself to be considered one).
