I came up with a random idea in my head
(since I'm such a Lucky Thousandth Edit Badge hunter), it's similar to Wikia achievements.
The idea is that you can collect achievements for completing a certain objective in the roleplay site. Like Wikia 'chieves, you get points from them, which you can then use to buy special items from the shop. (Perhaps we should add a new section in the shop where you can buy items exclusive obtained using the points?)
My examples of a few achievements would be:
Create your first character;
Reach Level 25/50/75;
Get a child character;
Deal 200,000 worth of damage in one attack during battle;
Use a Time Capsule...
Well, you get the point. What do you think about this suggestion?
