Deadball
Deadball Second Edition is a platinum bestseller on DrivethruRPG. This means it's in the top 2% of all products on the site. Its back cover has an endorsement from Sports Illustrated Kids.
It's also not an rpg I'd heard about until I discovered all of these facts one after another.
I was raised in a profoundly anti-sports household. My father would say stuff like "sports is for people who can't think" and "there's no point in exercising, everything in your body goes away eventually." So I didn't learn really any of the rules of the more popular American sports until I was in my mid twenties, and I've been to two ballgames in my life. I appreciate the enthusiasm that people have for sports, but it's in the same way that I appreciate anyone talking about their specific fandom.
One of the things that struck me reading Deadball was its sense of reverence for the sport. Its language isn't flowery. It's plain and technical and smart. But its love for baseball radiates off of the pages. Not like a blind adoration. But like when a dog sits with you on the porch.
For folks familiar with indie rpgs, there's a tone throughout the book that feels OSR. Deadball doesn't claim to be a precise simulation or a baseball wargame or anything like that---instead it lays out a bunch of rules and then encourages you to treat them like a recipe, adjusting to your taste. And it does this *while* being a detailed simulation that skirts the line of wargaming, which is an extremely OSR thing to do.
For folks not familiar with baseball, Deadball starts off assuming you know nothing and it explains the core rules of the sport before trying to pin dice and mechanics onto anything. It also explains baseball notation (which I was not able to decipher) and it uses this notation to track a play-by-play report of each game. Following this is an example of play and---in a move I think more rpgs should steal from---it has you play out a few rounds of this example of play. Again, this is all before it's really had a section explaining its rules.
In terms of characters and stats, Deadball is a detailed game. You can play modern or early 1900s baseball, and players can be of any gender on the same team, so there's a sort of alt history flavor to the whole experience, but there's also an intricate dice roll for every at bat and a full list of complex baseball feats that any character can have alongside their normal baseball stats. Plus there's a full table for oddities (things not normally covered by the rules of baseball, such as a raccoon straying onto the field and attacking a pitcher,) and a whole fatigue system for pitchers that contributes a strong sense of momentum to the game.
Deadball is also as much about franchises as it is about individual games, and you can also scout players, trade players, track injuries, track aging, appoint managers of different temperaments, rest pitchers in between games, etc.
For fans of specific athletes, Deadball includes rules for creating players, for playing in different eras, for adapting historical greats into one massively achronological superteam, and for playing through two different campaigns---one in a 2020s that wasn't and one in the 1910s.
There's also thankfully a simplified single roll you can use to abstract an entire game, allowing you to speed through seasons and potentially take a franchise far into the future. Finances and concession sales and things like that aren't tracked, but Deadball has already had a few expansions and a second edition, so this might be its next frontier.
Overall, my takeaway from Deadball is that it's a heck of a game. It's a remarkably detailed single or multiplayer simulation that I think might work really well for play-by-post (you could get a few friends to form a league and have a whole discord about it,) and it could certainly be used to generate some Blaseball if you start tweaking the rules as you play and never stop.
It's also an interesting read from a purely rpg design perspective. Deadball recognizes that its rules have the potential to be a little overbearing and so it puts in lots of little checks against that. It also keeps its more complex systems from sprawling out of control by trying to pack as much information as possible into a single dice roll.
For someone like me who has zero background in baseball, I don't think I'd properly play Deadball unless I had a bunch of friends who were into it and I could ride along with that enthusiasm. However as a designer I like the book a lot, and I'm putting it on my shelf of rpgs that have been formative for me, alongside Into The Odd, Monsterhearts, Mausritter, and Transit.
