I’m glad you are figuring it out. A quick formula is 1 - (0.70^n), where n is the number of dice. ^ means to the power of. Basically, you calculate the odds of all failure and subtract that from 100%. That gives the change of succeeding at least once.

No worries. I’m just being prudent for any potential « followers » of the Orange Catholic Bible. :)

I know you figured it our through looking at all possibilities. Still wanted to comment on this specific situation. You’ll roll 8-10 on the first die 30% of the time. So 70% of the time, you’ll have to roll the 2nd die which will get 8-10 30% of the time. 30% of 70% is 21%. 30+21 = 51%

4) ldf & rdf (0.7 * 0.7 = 0.49) Possibility 1. 2 & 3 have at least 1 success (8-10). 0.21 + 0.21 + 0.09 = 0.51.

They are independant but you are looking for at least one result of 8-10. So we have left die (ld) & right die (rd). Each die can be success (s) or failure (f). You have 4 possibilities: 1) lds & rdf (0.3 * 0.7 = 0.21) 2) ldf & rds (0.7 * 0.3 = 0.21) 3) lds & rds (0.3 * 0.3 = 0.09)

For one d10, you are correct but the statement was for two d10. To get at least 1 die to get 8-10 among the 2 dice is 51% Basically, you have 70% of each die to not roll 8-10. 0.70 * 0.70 = 0.49. So 49% of not rolling 8-10 and thus 1 - 0.49 = 0.51. I didn’t need AI.

Which game(s) would be best used to emulate the Rocketeer in the comics?

It’s a public library with rooms to play games and you can borrow games to play at home.

Maybe that’s their plan? Pinkertons find pre-released MtG cards in possession of WotC union member.

Are you thinking about their use against organized labor during the late 19th and early 20th centuries?

Did you know you only need a small brain to make silly little drawings?

How about Disruptcraving 2? Famine Fracture 2: The gluttony?

She wants to feed you like a mama bird to her chicks.

Botticelli!

Since you are posting now, I see you didn’t accept Blue sky’s statement on your existence. Good job asserting your existence!

While some purists restrict the "OSR" label to games emulating OD&D and/or Mentzer Basic, others consider anything from the hobby's first decade fair game; thus, having first been published only six years after OD&D, under the broader definition you could technically write an OSR game based on this:
