ADVERSTISMENT (PUBLICIDAD) JUST THAT. Or sell the game, just one "buy" to download software and connect to the server. Just 1 pay. If someone can not pay for it, bad think (but that people either is going to play right now: selling tokens)
So if you sell the game just one time for every new signer in people (and not selling tokens) then... at least YOU WILL HAVE A JUSTICE GAME FOR ALL US (ALL US, WE ARE THE CUSTOMERS, THE BUYERS) AND THE BUYERS OF THE GAME, WOULD BE PLAYING AT A MORE SAME CONDITIONS, NO MORE MONEYS DIRECTLY PARTICIPATING GETTING MORE AND MORE POWER, AND MORE, AND MORE, AND MORE... TILL THE INFINITE
If some one can not pay,buy, to download this software just one time (10-20-30-50 dollars, etc) he is not going to play this game right now selling tokens, may be he tries at the beginning to know this game, and a few days laters, or weeks, or 2-3 seasons (months) he will get worried, and stop playing. AT THE RICH COUNTRYS WILL BE THE SAME, the most rich people at the most rich countrys will play so far away, and the less rich people at this most rich countrys will play a lot, but no so far away like the most rich of this sames countrys. ALLWAYS CLASIFICATION THE MANAGE LEVEL, AND THE SUCCESS OF THE GAME BECAUSE SELLING TOKENS...
NO ANY FAIR PLAY FOR ANY ONE. FROM THE POOREST PEOPLE TO THE RICHEST PEOPLE.
