One more (timely) thought on this change from a more legalistic perspective....
Look at what has happened JUST THIS WEEK with the U.S. Government shutting off access to some of the OFFSHORE Poker/Gaming sites.
Even before the new "Greens Fees" were added, there were 2 key differences (probably more) that WGT has from those other sites:
1. WGT is ONSHORE - located inside the U.S. - and assumedly PAYING its share of taxes from revenue;
AND
2. There is no "Cash Out" - no way for participants to physically carry away $$ from this game.
Leads me to SPECULATION (clearly marked as such).....
This move with the Greens Fees MIGHT in some way have to do with insulating and differentiating WGT further from association with the "G" word.
Just something I thought of.
