I hear ye on this. I started out at 16 going to music college, but because of my views on music I could never bring myself to write anything that would sell. I just couldn't bring myself to do it, it felt wrong then and it still feels wrong now(it hasn't stopped me from playing music mind).
Now I'm set-up to do a degree in "Computer Games Programming", while it is a love for me gaming I find it much easier to treat it as a business. While I may detest business ethics in general I have found it easier to stomach them when it comes to gaming.
