I'm about to make a small, simple game, you can say another tetris clone. I'm ashame (don't get me wrong) to charge money for this game. So, I'm thinking of publishing it for free. Of course, I'll add some advertisement in game that will present other games from my site.
So, dilema is... Will the people play this game more because it's free, or will they play it more if they pay for it ($10 for example)?
