Mine is a percentage based dice game. I obviously had to be the manager of both teams but tried to be realistic in the decisions I made. It's a little hard to describe here, but I took the player stats and plotted them out over 1,000 plate appearances. Using three ten-sided dice (red, white, and blue), a player card looks like this:
Betts
HR 052
3b 060
2b 137
1b 293
BB 425
HBP 438
K 586
G 715
F 000
So roll the three dice. Red 2, White 7, Blue 1 = 271. 271 fits between the 137 and 293 on Betts' card, and therefore that's a single. I then have a separate chart indicating where the single lands and whether it's a soft single or a hard single. That matters, obviously, if you have a runner at second say, and the difference between hitting a hard single to left or a soft single to right center is the difference between scoring that runner from second or not. Also a separate chart indicating where grounders and flies/pops go.
Here's Devers playing card, to see how different it is from Betts
Devers
HR 043
3b 043 (meaning that his card cannot produce a triple; more on that in a moment)
2b 092
1b 220
BB 298
HBP 298
K 545
G 766
F 000
That same 271 roll for Devers is a walk instead of a single for Betts. A roll of 050 is a homer for Betts but a double for Devers. A roll of 393 is a walk for Betts and a strikeout for Devers.
Now, you see that the HR and 3b numbers (as well as BB/HBP) are the same. That means that you can't roll a triple on Devers' card (nor can you roll a HBP). That's because Devers had zero triples and zero HBP this year. In order for you to get a triple for Devers, it has to be rolled on the pitcher's card. Here are two pitchers' cards.
Sale
HR 018
3b 023
2b 058
1b 165
BB 220
HBP 243
K 627
G 780
F 000
Pomeranz
HR 035
3b 038
2b 102
1b 253
BB 381
HBP 392
K 584
G 784
F 000
So a 355 roll is a strikeout for Sale and a walk for Pomeranz. A 247 roll is a strikeout for Sale and a single for Pomeranz. A 600 roll is a strikeout for Sale and a ground out for Pomeranz. If say Pomeranz were facing Devers (obviously they're teammates, but just to show how this works), Devers could get a triple ONLY if 036, 037, or 038 were rolled *using Pomeranz'* card.
We determine which card is used by simultaneously rolling two six-sided dice (one for the batter, one for the pitcher). The die with the higher number represents which card we are going to use. In the case of a tie, if it's a same-side matchup (R/R or L/L), we use the pitcher's card and if it's an opposite side matchup (R/L or L/R) we use the batter's card.
This game is WAY WAY WAY simpler than stratomatic. That's on purpose. I love stratomatic, but it's very complicated. I wanted to create something easy to use so that I could play a game in 10-15 minutes or less. This is super simple (I could make a variation using actual L-R splits, but that's a lot more work) and very fun to play and yet after a full season, the season-ending stats are remarkably similar to their actual stats the cards are based off of.
I had fun and years ago made single-year player cards for some of the all-time greats. Ruth, Maris, Yaz, etc. Some of their numbers are just insane. Anyway, this is a very fun way to play baseball games for anyone who likes board games and who likes baseball.
And yes, I'd love to market it but have NO idea how to do that or if it's even worth it. I think there's a market for it somewhere though.
