Shaun Austin (born in Australia) is a part time game designer (really just a hobby designer).
Although he web-published some of his own designs, he is best known for his contribution to Oversoul Games range of PnP tabletop and board games.
Quote from the man himself:
"Game design is a hobby that I find enjoyable and a great way to relieve stress. I am probably not as dedicated as some but would rather share my somewhat adequate attempts rather than hide the work away. I have 14 games to my credit on BGG but more than 50 incomplete ideas on my hard drive, So expect more from me as the years go by! (But don't expect it quickly as I would much rather play games than design them)."
