Just wanted to say that I have been following Atavism for a few months now and was waiting for Unity 5 support before I purchased. I now have it and within a couple hours of reviewing Chasles YouTube videos on installation I was able to get it up and running locally! I am very happy and look forward to seeing what I can do over time. If you are interested in Atavism then do your homework and it wont be hard to setup and get it running.
