The "#THAC0 is not subtraction" argument is especially infuriating to me, because it's popular on #reddit, and dependent on the idea that #DungeonMasters were supposed to announce opponents #ArmorClass to players. That's a really amateurish style of old school. No adult should play like that, or defend play like that.

Still, it's maybe not as bad at whatever the fuck dungeonsdragons.fandom.com/wik is trying to say.

Kids on #reddit got worked up over #THACO this week. The most common complaints were subtraction is hard on the brain, that #THAC0 is *not* subtraction, and THAC0 is proof #2E ruined #ADnD.

I've been thinking about different editions of #TTRPG and especially #DND. I find that I really prefer the older editions of the game, #THAC0 and all.

The main reason is that those versions tend to have fewer gamey mechanics.

Take death checks in 5e D&D. Every round you make a roll to see if you live to fight another day or not. Three failures, you need a way to raise the dead or a new character sheet.

Personally, I like certainty. I tend to have a lot of bad rolls and I don't like leaving things up to chance or fate if I can help it.

Give me the countdown to -10 HP or dead at 0. Certainty is comforting to me in that situation. I don't want to leave it up to random chance and a cruddy luck streak.

I also don't like system mastery and thinking of characters as "builds".

I don't want to have to go through chains of feats or pour over splat books to make the perfect character. It bores me to tears.

I have no problem with folks who enjoy that. There's no bad-wrong-fun with that, just not my thing.

Give me the base book, maybe a splat for inspiration, but I don't want to have to look through multiple books at the table if I can help it.

A week or so ago, I was watching a video on older versions of #DnD and #THAC0 finally really clicked hard with me. Once life settles down a bit, I'm going to work with members of my #Pathfinder group to develop an #ADnD2e game loosely based in #AlQadim as a backup for when we are missing one or more players.

I'm dying to get back to AD&D2e. That was the game I started with and that's the version that still really excites me.

I'd happily play some version of Basic D&D or one of the retro-clones, but I think if it's going to happen at all, I'll have to be the one to run it. But that's fine, I love the freedom of the earlier editions to tell a really fun, engaging story for my players.

Ontem eu dei boost num post falando sobre #THAC0 e, ao ler os comentários, fiquei chocado ao notar tanta gente considerando o sistema complicado. Como assim, gente?! O sistema não exige que você faça nenhuma integral tripla com mudança de variáveis não, você só precisa somar e subtrair. O que tem de tão incrivelmente complicado nisso?! rs #RPG

I would be so much better at math if I had been allowed to play #DND as a kid. #THAC0

You wanna buy this pizza? It's $20. I'll spot you $4. That means you need to come up with ______.

There. That's THAC0.

Just saw a post saying that THAC0 is unnecessarily complicated. I totally disagree, it is quite necessary!

How else are you going to hit an Armor Class of zero? Magic?

Cover art by Jeff Easley for the Advanced Dungeons & Dragons 2nd Edition Player's Handbook (1995). Nicknamed "The Charge", it depicts a warrior with a battle axe smashing down a wooden door with his two party members close behind.

I'm "for my first D&D games I used THAC0 math for for attack roles" years old.

Yes, "pen-and-paper RPG" or PnPRPG. I'm #GenXennial (formerly known as #GenXY / 80s ). Even though we're now using gadgets, and the web, it's still #PnPRPG ,#TTRPG for me is different. ^_^ LOL. I still prefer #THAC0 ! All hail THAC0! #RPG #gaming

@Alexander_Anotherskip_Davis I've never had that reaction from an actual player, once they understand the "automatic +5" footnote. I think for a lot of them, that insta-bonus gives the feeling of a "critical hit."

But if a player doesn't like #THAC0, they can still use the original attack matrices (even when other players at the same game table use THAC0), because the two systems have the exact same probabilities to hit. Nobody is disadvantaged by choosing one mechanic or the other.

I recently recreated these #THAC0 tables in Google Docs (because I misplaced my original Word files), so if you want to use them, here are the links:

Player's THAC0 Table: docs.google.com/document/d/1IE

DM's THAC0 Table: docs.google.com/document/d/1O3

(I just committed myself to maintaining those links forever, didn't I?)

There are three *negative* fighter levels added to the DM's #THAC0 table because of an obscure (and comically sexist) rule on page 88 of the DMG.

There's actually something worse than being a zero-level NPC in First Edition #ADnD -- "sedentary females" are negative-third level NPCs!

It's very important that I remember this distinction, for situations where PCs get in fights with scribes and serving maids.
