Paid Tiers
The paid tiers are tiers that you can purchase, once purchased this is linked to your game account forever, meanwhile, you will earn tiers for 30 days with each credits purchase.
If your temporal tier earned with a credits purchase is higher than a permanent purchased tier, you will be able to play with the temporal tier, when the month is elapsed you will be able to continue playing with your purchased tier and keeping your already created character without the loss of it's customizations.
As higher is your game tier you will be able to make a more excentric character, for example: BBW or SBBW, Muscle hypertrophy, Gigantomasty, Elfs...
