Fate is a popular system to use for many RPGs. It part of the Fudge family of RPGs and developed a large following of its own. Recently it has concluded several kickstarters, a new Fate Core, and Fate dice (which are perfectly suited for Fudge as well).
Fudge/Fate is one of those system that always in my "I will get around it" bin. So the price was good on the kickstarter so I got in for a single pack of three sets of dice.
That one barrier down to running a Fudge/Fate game as I have extra sets to for players to use.
The following picture shows the dice I got alongside a white set of Fudge dice I had since the late 90s.
