There's at least one major 2E-inflected retroclone out there, as far as I know, but it's by a terrible person* and I won't mention it to promote it. For aesthetics, I would probably suggest Castles & Crusades, although that's kind of its own thing.
* Worse than you are guessing.
I am aware of "For Gold and Glory" as a 2E retroclone. I don't know anything about the designer. I did pick up a POD copy. Hope I didn't make a mistake.
I want to like C&C, but I'm not a fan of the SIEGE engine, adding levels to every check and getting very high numbers, plus the writing/design is just really sloppy. I have the main books, but I'm just not a fan.
Are there mechanical things from 2E that you would enjoy playing again, or is it more about vibes and aesthetic?
Psionics system
Specialty priests
Great settings that don't require mechanical translation to a new system
My favorite Monster Manual for any edition of any roleplaying game
But what I miss the absolute most about 2E is predictability. I can reasonably guess what damage the party can do to an enemy, without concerning myself with exploding dice from Savage Worlds, massive critical effects from Pathfinder 2e, bonus actions from 5E, etc. I can also understand healing and how much damage a party can withstand. There are too many factors, special powers, etc., for me to reasonably anticipate what a party can handle.
Ever since 3rd edition, I've become a Killer DM. I simply cannot plan for anything. It's all cakewalks until a TPK ends a campaign.
What I don't like about most other OSR games is the "dungeon" focus. OSE, Shadowdark, etc., all assume stuff like gold = XP, skimp over exploration rules, have monsters that have no place in a world ecology or information about how to use them in a setting - as if they're all designed for monster hotels. In 2E we rarely went to a dungeon, and even when we did, they were more like 5-room dungeons from modern design. It was cross-country, urban, open seas, wilderness survival, etc.
