What is the first thing to do before beginning the project?

I want to make a game, but I don't know what is the first thing I should do before making one.

Before Unity3 was release, there was a demo island and when you clicked new scene, it leaves all the assets behind. However, since it is gone. I can't get those assets. I try downloading but it gives me error. So I plan on making my own assets or similar to that one. So what is the first thing to do?

go to file-new project-import pakage

Hello

So if you are new to unity I really reccomend you looking up for some tuts:

Good Luck.
