Choice of Games LLC has worked very hard to ensure the contest is run legally and to protect ourselves from any issues with that. Other people do other things, but we consulted a lawyer who specializes in contest law and helped us ensure that our contest is fully legal. We do business in countries around the world and cannot risk running a contest in one of them illegally because we took some kind of shortcut with our contest.

On a more practical level, the cost of adding even one more just Anglophone country to this contest would have doubled the lawyer's fees, which were already substantial. The legal work to ensure compliance with additional nations' laws on contests would have been quite expensive, and Choice of Games is already spending a substantial amount of money to fund this contest, without any guarantee of the number of entrants that it will produce. If we hold additional contests in the future, we may be able to revisit that decision, but for this year we had to limit our overall budget for the contest.
We're sorry to disappoint people, but you can still likely publish a Hosted Game; if you use the guidelines we've published, and write a 100,000 word game, your Hosted Game could see very good sales, comparable to @cataphrak, @JimD, @Lucid, @Eric_Moser who have had great success in our Hosted Games program.
I hope this will be the last word on our contest eligibility.
