I have written a boilerplate projet for Unity 5, the ideia is a project with basic functionalities that every game should have, such as:

• Intro Scene with the logo and name of your game, with FadeIn and FadeOut.
• A Basic Menu, with Play, Select Level, Options, Cast and Quit buttom, which Select Level, Options and Cast will open a slide section with the informations.
• Pause System.
• A Basic Game State, to control the states of the game.
• GameManager.
• (And of course), it can be customized easily.

Can be useful to make you focus on the core of your game itself, and no something else.

It’s on Github!

I’ll probably add more functionalities. Pull Requests are welcome.

Good luck everyone!
