Wait so we will be allowed one airline per world?
There will be a "Token" system involved. Details herein:Every 12 hours a free token is handed out to every player (all players will start with a default of 35 or 40 tokens).
When you get 30 tokens, you can join a world. As the system stands at the moment, there is NO extra fee for JOINING a longer game or a shorter game.
You're allowed one airline per world.
IF by some fluke of fate you're in ZERO active games AND you have less then 30 tokens, you will be allowed to join a public world at the cost of whatever tokens you have on hand.
Tokens will also drive the private world creation system (will not be available with initial launch, gotta come up with costing formulas primarily). NO exceptions will be made to the 30 tokens to join a private world rule.
Additional paid Tokens will also be available for purchase in bulk lumps (Exchange rate being worked on at the moment, don't ask how much it will cost.)
Any inactive account will have its free tokens reset to 50. paid tokens will be unaffected.
NO other caps will be in the system. i.e. if you had 30,000,000 tokens, you could join 10,000,000 worlds (if there were 10,000,000 worlds available).
Possible features to be seen relatively soon, however unlikely to be immediate, related to tokens: Bonus for top few players in a PUBLIC world only, including but not limited to top X by value, top Y in each continent by value, top Z in (otherstat). Unlikely to be huge, and likely scaled to the world's player count.
Other cosmetic things may be sold for tokens (i.e. alternate site skins).
