I think actually uh, the staff turnover isn't insanely high.
I think BestRP/Unbound Travels, Apollo (?) and Paradise cycled through even more staff at a faster rate aside from the hosts and a fewer higher ups.
UT 1st host Pixelsshadow lasted a year (or six months?), Jamie lasted a year, Yithani 2 months?
Purlek (BestRP) lasted 3-5 years but he didn't give a fuck and was making money (like 5k/mo) and threw all the fire extinguishing to Emmanuel Bassil (who fucked off and joined the Lebanese army or something).
Edit:
Now that I remember, Aurora first host/headmin Chaznoodles (also now LGBT and the captain in this spoilered comic) lasted ~10 months, new headmin mrimatool then lasted 4 months (Fsphere hosted for a few, went to a shadow something), host/dev/headmin Skull lasted until today (10 years).
@The Bogwater Rises remember Alberyk ? He was the reason Sue could do whatever they wanted.
It's complicated. They cross-contribute to specific codebases but generally 14 devs are ex-13 devs of
specific servers (particularly /tg/ and citadel) . 14 is a remake of 13 in C# with it's own engine.
Then again 13 devs vary wildly from relatively normal Nebula and Goon devs to off the wall troon devs on ERP servers (Looking at you, fallout and VORE downstreams) and /tg/.
Gecko's server code has +NIGGER so all the troons committed seppuku or are too scared to say so.
