Why not make a high quality game with custom graphics, musics and scripts, all made by yourself after writing the story, world and scripts over a total of 3 years, and release it for free? It's all stuff made by you, and you didn't pay anyone else.
Tell me. Why? There would be little compensation for your work.
-or-
Pay other people (professional pixel artists, professional music composers) to make graphics and music for your game, and had it out for free.
Tell me. Why? You are spending money for the enjoyment of others, why not ask for 5 bucks from each person that plays it, so that you can break even from spending 1000 bucks to make a game that is excellent and more than mediocre?
