Just finished a wonderful session with Tim Shorts and the Monday night miserable bastards crew. Best part was we ended on a cliffhanger.
We had just found a abandoned village, some of it had been destroyed. We fought a few skeletons, then went into an old house. There we found a skeletal baby (I believe), which had eight large gold bricks.
After that a booming voice said "now your mine"
I really like playing bx or lighter games on roll20. Tim has a really good way of going about things, and handling specific mechanics. It's almost invisible.
Typically with ability checks (which don't happen often) we roll d20+level+stat mod.
It's basically bx with ascending ac, and mostly d6 damage. As well side initiative.
There's honestly not much I'd change, if I wrote some rules.
I recently had a discussion about ability checks and mechanics with a player on roll20. I may have been using them far too often. I was also using roll under. Tim doesn't typically give us a dc number. More so we roleplay it out. And on occasion we will have to roll.
Another thing I saw recently was using percentile dice. I may start doing that actually. Pick an amount and have a player roll.
Anyways just some brief thoughts.
