ii just believe i can play for free, becuase there are many ways to get incomes...
What makes you believe that? The are only four ways you can play it for free:
- BB developers do it as a gift for you (for what ever reason)
- You are a close relative to BB developers and they love you
- Somebody else pay for you for what ever reason
- You are needed here because without critical mass of players it will not be interesting for those who pay
As you can see none of this four is really for free as somebody else has to pay for what ever reason and fourth is just a really upsetting reason to get it for free.
You always choose your own.
