I always wanted to create a game on my on style.If i could, i would make a game based on the Percy jackson´s books, and would make a gameplay similar to prince of Persia(because of the quick reflexes) and god of war(because of the magic attacks!).I don´t know if people would like but i know i would!
The game would have 15 levels with two boss for eachone.
It would be singleplayer of course...most of the multiplayer games are lame...
