Goodsprings Tutorial Town: http://falloutpenandpaper.wikia.com/wiki/Goodsprings

I used the vault to help me with the rules, and I don't really care if the article is almost word from word, with a few variations. As long as I can get my point across, I'm pleased. The Crafting List and Goodsprings aren't down. Additionally, this campaign does not fit into the Fallout continuity. There was no Vault Dweller and all the settlements exist simultaneously, as well as out of order. Goodsprings replaces Shady Sands since Shady Sands went on to become NCR and I really liked the atmosphere and missions of Goodsprings from New Vegas. I will probably add some custom towns that take place in Chicago.

Made a wiki for the game.

So hmmm. I don't get combat.

When Jerry the Punk attacks the Boatfly, your description says he misses when his attack turns into a 10.

But, you are initially rolling a d20 and computing it into this formula.

Soo..is it impossible for Jerry the Punk to hit? A 16 on d20 is pretty high roll. 17,18,19 and then the crit 20.

I'm just confused, because I don't see where the actual to hit number needed is, and why the final number of 10 is a miss instead of a hit.

Takes for responding. It's because the range modifier and skill modifier changes the outcome. Sure, you can be right next to someone with a shotgun (and while its unlikely to miss), you still need to have the right skills to actually use it properly. The Bloatfly had a higher Armor Class than 10, so Jerry missed.
