I believe a lot of it depends on what you want to do within Unity, but whenever someone asks me this question, I direct them to Brackeys youtube channel. Very good tutorials to build a good foundation of what is possible. This knowledge can then be used to go down a more specific path of learning.<p><a href="https://www.youtube.com/user/Brackeys" rel="nofollow">https://www.youtube.com/user/Brackeys</a>
