Tar, I daresay players from other countries would also be keen to play virtual courses in Continental Europe, Japan or Australia, etc., especially if we are talking about some truly superb courses that host top events on the European or Asian tours.
Australia seems pretty heavily represented on WGT.
Japan maybe not so much, but that looks like a great market for WGT to shoot for because it is keen on golf and keen on computer games. Go for it!
