A lot of time making Selections are spent on two things, gaining activity and creativity. Standing out in more common terms. Here's a few screens screenshots that basically sum up my thoughts on what personally makes a good Selection.

Simplicity is key! You don't have to go overboard all at once, a steady stream of quality content is better than a dump of information in ways that can be confusing for the roleplayers your trying to attract. Be unique! be neat with matching fonts, dividers, and easy access to claiming pages, forms and the rules. And if it pleases you it will please your audience, good quality pictures, gifs, and things that make one's imagination pop are crucial! Aesthetic collages have been a godsend as they convey all of this in one single picture!

My experience with Fandom based Selections was a scattered confused mess. It is truely difficult to fit all those big worlds into your little one.

Being unique can be a Game of Thromes Selection or a Supernatural Selection or even a Selection that is completly unique to you!

Flesh out your ideas, make them into a world rich with lore andbackground. One that others will be hooked into the moment they read the first page.

Then set your collective imagination loose and see what wonders can come!
