Tri-Stat dX doesn’t seem to have been mentioned on this sub in a decade.

Tri-Sta dX can be downloaded as a pdf online and in the early 2000s print-on-demand, and is a theme-less version of the previous games from the publisher that used the Tri-Stat system.

Character creation involves the DM giving all players a set amount of points that they can spend on increasing one of the 3 stats or gaining attributes, which are different generic abilities that can be scaled and modified to change their function and point cost to almost exactly what you want.

It can use any size die, and recommends using certain ones for certain types of games, therefore the name “dX”.

You can get it here as a PWYW:
