24BLUE is a minimalist role-playing game based on the 24XX system by Jason Tocci. 

It is classless, setting flexible and light.

This was born when I wanted to run more OSR adventures with less rules and work.

You can use it in any setting you like or even create your own using tables in the game.

Adapting from other systems using the guidelines requires little effort.

Easy to adapt to one-shots and campaigns.

The rules are split in 4 quarters of a page: 

  • A quarter regarding general rules of play
  • A quarter for character generation and advancement
  • A quarter for GM guidance 
  • A quarter for adapting creatures, traps and items from other systems

At the back, tables for:

  • Setting creation
  • Adventure
  • Items
  • Enemies

This rules are mostly compatible with any other 24XX hack, including mine and from a lot of folks!

I've been thinking about how to reconcile the use of traits (freeform-y words or phrases) and skills in 24XX (in a different way from how 2400 does), and you've managed to do it very elegantly!

Glad you liked it! :)


The "ADAPTING" section has a great explanation of how to run opponents in 24XX games generally.
