RPG a Day 2015 Challenge – Day 25

Welcome back to the #RPGaDay2015 challenge series, here is another topic I had a hard time coming up with an answer. But let’s go, this one is as short and sweet as yesterday’s post.

Day 25 – Favorite revolutionary game mechanic

The single mechanic, one roll, roll high (such as in the D20 system, but not exclusive to it), simple and elegant. In the case of the D20 System being that I was mostly a D&D player for the longest time, that core concept eliminates a lot of the clutter of previous editions.

Like I said on Sunday’s post, I’m a big fan of roll high simple rolls! Keep the math simple and easy to follow. We understand the idea that rolling high is good instinctively. That for me was a simple shift, but revolutionary in all its possible applications.
