OSR Lane Final
This one feels like a heavyweight championship all on its own. It's also a rematch, forty-odd years in the making, of the AD&D vs BECMI argument that split the gaming world in the early eighties. I was on the AD&D side then. I looked down my nose at Basic D&D because I already played Advanced D&D. The irony of where I've landed is not lost on me.
AD&D 1e
AD&D 1e has a mini-game for almost everything. Figuring out the right set of rules for your table has always been part of the fun. THAC0 takes a lot of heat, but Weapon Speed Modifier and weapon type versus armor class were there too. Poison types, mining rates, construction costs: more options than you could keep in your head, and a specific pleasure in finding the combination that worked for your table.
That toybox is also a relationship. Decades of memories live inside those rules. Kreega Two-men-tall, the half-ogre fighter who rampaged through my Riverton Campaign. Maine, the spoon-flinging halfling thief from Hochheim, just concluded. Those characters ran on this chassis and couldn't have existed anywhere else.
AD&D rewards the kind of player who wants to go deep. The mini-games, the subsystems, the Dragon Magazine expansions: all of it is there for the table willing to dig.
I find myself looking back at AD&D the way you look at a place you grew up. The memories are vivid and the floorplan is still in my bones. I know where everything is, even the rooms I never used.
OSE
OSE is slim, fast, and fun. The writing is clear and well organized, which is not something Gary Gygax was ever accused of. You can run from the page without translation, find what you need without hunting, and hand the book to a new player without apology.
The design choices compound over time. Customizable thief skill advancement from Carcass Crawler is exactly the kind of thoughtful addition that shows OSE isn't just a restatement of the old game. It's a refinement.
OSE is also the common language of OSR gaming right now. When the community writes adventures and supplements, this is the chassis they're writing to. That portability means everything you run in OSE connects to a living ecosystem of material.
I'm looking forward to rewriting some of my earlier campaign material into OSE. There are little gems waiting underneath the scaffolding, and I want to find them.
The honest case for the loser
AD&D has a special place in my heart, and I find myself looking there for ideas more often than I expected. The mini-games, the subsystems, the sheer appetite the game had for everything: none of that goes away. If you want advanced play and don't mind the scaffolding, AD&D is still the answer. And if you're having fun and not hurting anyone, you're playing the right game the right way for you. That was true in 1979 and it's true now.
The pick
OSE, and it comes down to where I am right now. Lighter systems, higher portability, and the promise of new memories crafted with friendlier rules. AD&D gave me Kreega and Maine and forty years of table. OSE is going to give me whatever comes next. The little gems that a little less scaffolding unveils are worth finding.
That's my pick. Who'd you have sent through? Tell me in the comments.
