Discussion Freemium

One thing I want to do with Eryou is make it free to play. However, since hosting costs a lot and it will use a lot of my time, I propose the following things:

Game is free to play as 1 character.

However, a player could pay for the following perks:
 * Character slot unlocks (up to 5). Would allow you to have another character, so that way you could have one character per class if you wish. Suggested cost of 500L for this as it would need to store a lot more data for an extra character slot.
 * JasX Premium required to play as a monster vs friends.
 * Purchasable wisdom crystals. These are gained by completing missions, and used to buy regular armor as well as levelups.
