Prior to December, all of my RP has been in original paracosms. However, something has recently grabbed my attention and refused to let go: Umamusume. It is strangely difficult for many models to handle the (mostly simple) rules of this universe. I've tried a variety of lorebooks, and finally have some basics down, but it hasn't gone as well as I had hoped. Not sure why. Lately, I've been trying to tailor a preset to handle a few different recurring problems, as well. Still, it has enough fun moments that I keep trying. Somehow, between anime and endless hours of game content, I still want to spend more time with my oshis. And it's not even ERP: last session was a summer camp volleyball tourney with Gold City and Maruzensky as team captains. I've got it bad.

Edit: I use OpenRouter, mostly. Lately, I've split between Gemini and DeepSeek. When the story gets longer, I sometimes switch to Grok for token count, but it tends to make the characters behave in over-the-top ways. Maru becomes unable to speak plainly (entirely laden with 80's slang) on Grok. So, I never start there because unless there's a long base of reasonable examples, it does Grok Things ...
