So basically, everybody feels "natural" playing the good guy first, then tries evil the second time around just to see what it's like. If every single game that has a good/ bad mechanic inspires people to do this it's time to reinvent the mechanic. For instance: does anybody know of a game where choices (not only dialogue, but also actions) actually make a character MORALLY grow?
You must've heard it.. if you're a normal, sane human being it is really hard to kill another human being in real life (outside of self-defense). Such an act really changes a person for ever. But in a game... characters are either A. some sort of soldier, which means they are "used to it"..which is funny cuz what is all that commotion about post traumatic stress disorder then (sarcasm)? Or they are B. magically immune to remorse, guilt, sorrow..unless it's in the script (not your choice).
I guess I'm advocating more 'realism' concerning morality in games. But that's probably when games stop being fun...cuz nobody wants to think too much when playing a game, right? Another possible scenario is: games start to look like movies (the metal gear problem)..which can be frustrating if you have to skip too many cutscenes.
Balancing gameplay and storytelling to create not only believable/ likeable characters but also a fun game is truly difficult. Even gaming guru's fall into countless traps in search of this 'philosopher's stone'. To me it just feels like they aren't trying hard enough... maybe cuz in the end gaming is business. They aren't experimenting as much as they did ..say...15 years ago. Basically they're playing it safe and we, gamers, faithful customers, get more of the same every year. It has even gotten so bad, you can actually confuse one game for another (inFamous, Prototype).
I think that the gaming industry has become complacent now that it is established. Now they don't have to worry about our wishes anymore... cuz we're eating whatever they are serving...including crap.
Thank god for the indies, who are still experimenting. Innovation, originality... words that they haven't forgotten.
