Free is for people who just wanna have fun screwing around in whatever setting while not showing much concern for how they write, or improving on their writing. If you want a good time fooling around with absurd ideas, it's the place to be. Great for goofy RPs or extremely edgy stuff; it's a playground of guilty pleasures and teenage desire. It's alright if you don't want to write anything too serious. I don't judge people for just wanting to have fun, I've hosted and participated in plenty of 'free' RPs in the past. Casual is for all levels. It typically attracts people who want a coherent plotline and more detailed writing, but don't want to write or read 6 paragraphs of fluff in every post like they're in a Steven king or Tolkien novel. Most casual RPs could probably be fit into free depending on the concept and the people posting if they stuck to dialogue, but there's this weird metric where people equate post length to quality, meaning that you won't see many people speed posting in there. It varies tremendously, but my basic idea for 'casual' RPs is anything that isn't absurd, or pretentious. It's where I spend most of my time in role plays, as I don't expect to be held to any nebulous and misguided standards while writing some stuff up. Advanced is for people who enjoy writing fluff and don't care about pacing when they dump buckets of exposition in a single post. I like to describe it as the [i]horribly pretentious doppelganger of the free section.[/i] It is most certainly a place where people who enjoy reading and writing flowery sentences flock to. But despite being flooded with very long posts, and uncommon vernacular, it seems that most advanced RPs are anything but dense. I play a little game sometimes where I take a 9 paragraph 'advanced post' and narrow it down to two paragraphs without losing any of the actual content. Advanced is a place for people who like to write [i]a lot[/i] of words. I see it as the least cooperative and/or least engaging section on the forums. Arena is a shadow of its former self. What was once a bustling community of a bunch of tools who thought that winning was more important than the experience of a fighter, now sits... Well, nobody. Fights are fun, but nobody really cares about them when you turn them into a contest. The entire 'competitive' infrastructure of the arena is a joke, but I know exactly why people liked it. People are too obsessed with winning/their characters though. I know I was. Rarely will you come across somebody who's humble enough too just be in it for the fight. In those cases, it's quite an enjoyable affair. Tabletop is... Well I don't know what it is. I guess you can use that section if you don't know what roll 20 and discord are? Nation roleplays are probably the best example of what advanced roleplays try to be. That's all I can say about that.
