A note about VIP.
It seems that it cumulatively tracks how much you spend in the game. It is not measured on a monthly or other amount, but total amount you have spent while you have been playing the game. There are levels you reach as your total spent reaches each one. When you reach level one, you continue on until you reach level 2. Once you climbed to level 10, there are no more levels. those that spend a lot will get there quicker. Those that don't will take longer.
Personally I would have rather seen a Monthly VIP system where you get perks for a monthly subscription fee like most other F2P games do it. But this is better in that the perks you get are permanent for your entire account and don't expire each month. And as you spend more, you reach the next VIP level - you never go backward.
I kinda like it.
