I admire your principles and your artistic talent. However, I do consider drawing and playing games to be of equal productivity. I measure productivity by output. Video games are unproductive because at the end of the day, all you have is points and e-money. While drawing does yield more doodles, that's all you're going to have. Only you and your friends are going to appreciate those doodles, similarly to points and e-money. Inspiring people does have its merits, though. Even if it's only an attempt.
