About the cost

Hi.

Why this game will cost something? Why not Free2Play?

It's about resources: improve the game, add/improve a content. That's all require human time and skills. I'm alone in the project and i can't cover all areas of gamedev,  say more: i hardly cover only coding area.
And this is an online game, here will be enough cheaters. So, paid account will filter a little part of them.

Financial scheme will be next: paid account and ingame shop.

Paid. The cost will be increased from 3$. Less content/features, unstable product, more risks - cheap price. More content/features, stable product, near to release - more price. You may buy the game at the early stage for cheapest price or may buy a stable product in future for higher price.
Ingame shop will offer only "skins" (clan's logo, color's for clothes, etc).

ANYWAY, BEFORE PURCHASE, PLEASE, BE SURE THAT YOU GET WHAT YOU WANT!
THERE IS A RISK: THE PROJECT IN EARLY ALPHA STAGE CAN NOT BE FINISHED!
