Sometimes you overthink things, especially when you want it to be "right" and cover all bases. Such was the 3d6 hack I was working on for combat and saves for Swords & Wizardry: Light. I wanted to make sure even if the gamers lacked a D20, the material would work for them.
It was going to take up space to explain it and it wasn't going to be a perfect fit, but I was aiming for "close enough"
So, leave it to my sister to come up with the obvious solution.
"There's an app for that, right? I mean, nearly everyone has a smart phone or a tablet and you're expecting folks to have computer access to print copies and distribute. So why not just use an app?"
See, there's a reason she's a published author.
Another example of not seeing the forest for the trees and needing an outsider to point things out.
Yes, there are apps for that. Free apps.
K, time to play on my Android phone ;)
