[@PaulHaynek] It's relatively easy to pick up, since the games themselves aren't really lore-heavy. If you want to learn about the setting (monsters, history of the world, etc.) I can recommend a few sources.

[Hider=Dark Magical Girl 1]Ever since sitting down and watching [I][URL=https://en.m.wikipedia.org/wiki/Puella_Magi_Madoka_Magica]Puella Magi Madoka Magica[/URL][/I], I've fallen in love with the idea of the dark, deconstructive take on the magical girl genre. However, the idea I have for a setting is… complicated. This is the closest way I can sum it up:
[List][*][I][url=https://tvtropes.org/pmwiki/pmwiki.php/Webcomic/SleeplessDomain]Sleepless Domain[/URL][/I] meets
[*][I][URL=https://en.m.wikipedia.org/wiki/Final_Fantasy:_The_Spirits_Within]Final Fantasy: The Spirits Within[/url][/i] meets
[*][I][URL=https://en.m.wikipedia.org/wiki/Attack_on_Titan]Attack on Titan[/URL][/I]
[/list]
As you can see from the mishmash of ideas, I find it… difficult to put into words, especially without a proper keyboard (read: using a phone).[/hider]
[Hider=Dark Magical Girl 2]This idea is slightly more straightforward. In the not too distant future, next Sunday A.D., Mirai City has become one of the fastest-growing and most technologically advanced cities in all of Japan. But in this world, there are two forces at constant war unable to be seen by humans: the Fae, spiritual beings that feed off of and induce positive emotions, battling Demons, spiritual beings that feed off of and induce negative emotions. While Demons have the ability to possess humans if their spirits have been broken, the Fae have their own way to counter them by creating magical girls. Seems fairly typical, right?
Well, it stops there.
In order to maintain their powers, magical girls must destroy and absorb the spirit cores of demons. However, there are only so many to go around. Eventually, an unwritten rule was agreed upon by the magical girls of Mirai City: each magical girl would take a part of the city as their territory, and could only hunt demons in that part of the city. Knowingly hunting in another girl's territory is grounds for a fight… and even death.
In a nutshell, this plot is inspired by [I][URL=https://en.m.wikipedia.org/wiki/Blue_Exorcist]Blue Exorcist[/URL][/I] and [I]Madoka Magica[/I], with a dash of [I][URL=https://en.m.wikipedia.org/wiki/Doom_(2016_video_game)]Doom 2016[/URL][/I] for good measure.[/hider]

I've had these ideas for about a month or two now, but I haven't been able to properly work on them thanks to not having a computer (or, more specifically, a physical keyboard to work with). I've had a little luck with the second as a 1×1, but I'd honestly like to make it into a group RP; I want to make the first one a small group RP, with perhaps four other players. Another issue I have is GMing in general. I have a tendency to either not do enough, or go completely overboard, when it comes to posting and interacting with players. The "overboard" could probably be summed up as "control freak-ing".
