Well, when you say you’re looking for games that are “satisfying” and give only two examples with no indication of why you found them satisfying, that’s not much to go on. All of these games are “satisfying” to many of us.
I do think this latest post helps give a feel for what you’re looking for. Let me see if I have this right: you’re looking for “game mechanics” with possibly an interesting frame story but you don’t really need that? Preferably more simulationist than solving hand-constructed puzzles? Unless the game is very short and has something to say that gets to you: I’m not clear when it is that you like the fiction versus not.
I don’t feel like there’s a lot of this in IF: most authors are more invested in the fiction or in the more “text adventure” style puzzle-fests. (edit: I also feel like most of these forms of games are much more highly developed elsewhere, so when someone experiments with adapting them to IF they’re often disappointing to someone who has played that genre before). But here’s a few more thoughts (don’t feel like you have to try all of these):
Olivia’s Orphanorium is a sort of time-management/resource-management game in IF form: “Sparky young entrepreneur Olivia sets out to fulfil her dream of running an orphanage. The beatings will continue until morale improves.” But there’s not that much there, so I doubt you’d like it much. Ditto Fine Felines which is much less of a cat fancier game than it’s a story of dealing with chronic illness.
You probably know that John Ayliff, author of Seedship, has other games, including the $10 Beyond the Chiron Gate which is sort of a spiritual sequel to Seedship.
I don’t get that you’re all that interested in puzzles, but there’s much more in that direction, of course. Lots of games that are interesting puzzlefests with light frame stories. Andrew Schultz has done chess puzzles (Fourbyfourian Quarryin’, Fivebyfivia Delenda est, etc.), or word puzzles (Threediopolis etc.) or (very US-centric) rhyming puzzles (Very Vile Fairy File etc.).
Arthur DiBianca does a lot of puzzlefests and also often experiments with “breaking the rules” and trying out adapting different forms of games to IF, so Skies Above is a slightly grindy game built around a bunch of minigames and the puzzles are just about noticing the clues to optimize the randomness to get the best chance of advancing as fast as possible. The Prongleman Job is very short but has an unexpected mechanical twist that some people thought was clever and others thought was unfair. Inside the Facility has a new release with a graphical interface where you can just click. Grandma Bethlinda’s Remarkable Egg is just a bunch of goofy puzzles.
What else? I wonder if Pace Smith’s Limerick Heist might click with you? Heist story written entirely in limericks, short enough not to outstay its welcome. She wrote one or two others if you like that one.
If you might like optimization puzzles, Captain Verdeterre’s Plunder is a game about extracting the most valuable treasure you can from a sinking ship where rooms get gradually flooded. So you play it a bunch of times to try and figure out the best course through. Sugarlawn is similar, but the premise is you’re a contestant on a game show and you have a limited number of moves. Play several times to solve the puzzles and find the hidden mechanics, then settle in to try and get a high score.
Language Arts was a sort of programming game around swapping letters around to make words.
edit edit: Junior Arithmancer is arithmetic puzzles but has that stringing spell pieces together feeling. Suveh Nux is also a “figure out what spells do/how to construct them” game. Kerkerkruip is a short roguelike… maybe not an amazing roguelike, IIRC the difficulty is mainly around choosing which order to go after the enemies in and figuring out their tells, and then just hoping the randomness doesn’t kill you, but eh, roguelikes. And I wouldn’t really recommend The Gostak, because I think it requires a fair amount of familiarity with parser IF conventions to get started figuring things out, but it’s a sort of conlang game where all the nouns are replaced with nonsense words and you have to figure out what they mean. Kind of a love-it-or-hate-it game.
