You can get up and running with the required software for the grand total of zero dollars. Everything you need can be downloaded free of charge with no catches. All you need is:

Unity Personal or Unity Pro version

C# programming knowledge.

This is not a book about learning how to program. You will need to know some C# and there are several other books out there for that purpose, even if I have tried to make the examples as simple as possible!
