Frankenstories is a Quizizz/Kahoot-like game for writing.
You provide a prompt, players respond to it, and then players vote after each “round” about which response they think is best.
You can get a free account to try it out for thirty days (without all of its features), and then it costs $100 per year (in Australian dollars – not sure the U.S. exchange rate).
I’ve embedded a video about it below, and am adding it to The Best Websites For Creating Online Learning Games.
I think it’s an interesting idea, though probably not that useful with English Language Learners.
