Start with shooter example or not?

I’m planning on creating a FPS game which has the same basics as the shooter example game you can download from the marketplace, but I’m not sure if it’s best to simply look on the project and do everything myself or create the game from that project. The reason I ask this is because I noticed that alot of headers and stuffs still had the name shooterproject (even though my project was named something else) and if I have to remake the GUI and change weapons etc I don’t know if it will cause me more trouble then good to start from the shooter game.
