Tachi is a rhythm game website that tracks your scores on all your favourite games, and provides awesome features like quests, sessions, rivals, and more!
We think it'd be in people's interest to have open, easy-to-use access to the millions of scores and sessions we have on Tachi.
There's no shortage of cool stuff you can do with this data - you could run stats to find out what charts people struggle on, how certain charts have gotten more or less popular over the years...
In short, you're free to do whatever you want with these large rhythm game datasets.
I hope it helps you out! I sure wish I had something this practical when I was starting out.
If you are developing stuff for Tachi and need some local data to play with, this is invaluable. Note that you can log into any users account with password as the password!
If you are a stats nerd, or just a rhythm game nerd in general, this is an excellent resource for doing any sort of analysis. Have fun!
If you have Tachi set up on your local machine, you can use just load-kamai-dataset or just load-boku-dataset.
