Take a look at the MESA Character Creator: build a Researcher Basemesh by mixing heads, outfits, and names.
The character creator is something I'm super excited about, and it is the result of many requests I've received ever since I launched the stream back in September. I've gotten so many requests to add new characters to the stream, and chatters have occasionally even invented characters in the lore around the stream that aren't even present.
After observing this behavior for a while, I realized it was a subtle indicator that there's interest around creating custom characters for the stream. Very similar to OC (original character) culture online, it feels like a sort of crowdsourced means of creating characters and virtual personas online, through which you can create content, roleplay, or build a library of personas.
I think there's something very net-native about creating characters that reminds me of playing DND or other roleplaying games. The only difference being, when you create a MESA character, you're creating an entity that goes off and interacts with other characters in its own way.
