I hope you don’t, like NoobCube suggested, look for a primer on game development, including things like modeling etc. If you do and don’t want to “waste your time reading a book”, it’s hopeless
As for Game Design, Jesse Schell’s “The Art of Game Design: A book of lenses” is pretty interesting, because it gives you 100 “lenses” through which you can look at Game Design. You might wanna check it out.
