So only games that are made from scratch can charge full price? What about reusing code? Engine? Animations? Textures? Lighting system? Rendering backend?.. Games are made of everything that came before, being angry about a game using assets that were originally developed for an older game is like being angry about a movie reusing props made for an older movie, should they burn all of the Christmas decorations between one movie and the next? Or can the studio hang the same glass ball on two different movies? Does that detract from the movie? Will you really only consider it’s worth the full price if all props were made exclusively for that movie?..
