Patient Gamers

Well you've already recommended the next best one. The dlc for Outer Wilds.;)

Not quite "time loop", but related: Return of the Obra Dinn. I need the developer to make another game with exactly the same mechanics.

There's a tiny game called Loop Hero where your hero goes on a literal loop around the world, facing enemies as they go and while you craft a world of out existence. Pretty fun.

Not a time loop game but has one of the best time loop levels of any game I have played - Titanfall 2.

Returnal is brutal but really fun.

The Mooncrash DLC for Prey (2017) isn't strictly a time loop game but it might have a lot of the elements that you find interesting.

Play the Outer Wilds DLC, if you loved the base game, you will like the DLC too

Slay the Princess is a relatively light game (largely narrative) that has this as part of its conceit.

Maybe Radiant Historia fits your bill. It's a JRPG by Atlus originally on the DS, with a remaster on the 3DS. You can time travel to different nodes in the story and the game will replay identically, which of the "loop" part. It has a branching storyline stemming from a choice early in the game, and you have to hop to the other branch to get abilities and information for the other.

May I recommend No-one has to die? It's a bite-sized webgame that I thought was really good, you can finish it in under an hour.

Also if you're going to play steins;gate I would recommend skipping the sequel (steins;gate 0). It's not good.

Try Hitman. All the characters walk around the world and go about their business, and it's up to you to plan out how to go between that and do the assaination after understanding movement routes and actions

Personally I would recommend watching the Steins;Gate anime rather than playing the game. The game has a bit of a confusing mechanic for making choices and reaching the true ending basically requires a guide. I also feel the story flows better in the anime, even if some details are left out.

Bioshock infinite comes to mind, even though the timeloop aspect of the game is entirely related to the storyline, no game mechanics use it.

Surprised I haven't seen Quantum Break in here. It's a pretty good shooter with some magic powers thrown in for fun. You don't get much say in the story, but it still kept my interest all the way through. And it has an interesting take on time travel, woven into the story quite well. It was made by Remedy Entertainment, before Control but after Alan Wake. Also I liked how they cast real actors in the game and made them recognizable. I picked out Courtney Hope in the game from seeing her in Control, even though her character is different in QB.

Cobalt Core is also timeloopy :3

Katana Zero

I was pleasantly taken by surprise when I got around to playing Angels With Scaly Wings. The title and the trailer had given me a very incorrect idea of what the game was going to be like. Once past the somewhat contrived set up, it ended up being a very well paced sci fi story that keeps throwing curve balls at you loop after loop.

timemelters?

You might enjoy the recently released Cobalt Core. It's really more like Slay the Spire in space, but the addition of a time loop gives a neat narrative framing to the deckbuilder mechanics.

Quantum Break might fit if my memories serve me well enough (it's been a while). It might only be time jumps, not loops.

Singularity was pretty good.

Oxenfree

Don't know if Time Travelers from Level 5 qualifies as time loop but I liked it. Seems it's only in Japanese, though. I hope they'll port it to Steam in English eventually.

Have you heard of Minit?

Not really my thing and haven't played much of it, but it definitely fits the bill.

There is No Time to Explain. It's one of those mechanics based platformers with crazy time loop story.

This is probably not your speed, but I can’t stop myself from mentioning Deathloop…

Also, and this is a bit of a stretch, but Day of The Tentacle was a great game with a time element… I’m reminded by this because I asked ChatGPT for a list of games that met this criteria.

Prince Of Percia: the Sands of Time It's an oldy, I don't know how it's aged, but you can rewind time a couple seconds when you make a mistake. Of course there's puzzles that make use of this mechanic and puzzles that make this mechanic useless and the story is all about time as well. I thought it was pretty fun at the time.

It's light on exploration and close to a visual novel, but for non-linear narrative, it's possible you might like 13 Sentinels: Aegis Rim.

I don't want to say too much about it, but Undertale is more about a different kind of loop structure, something unique to gaming. If you like it, you may also like Pony Island, which does work with loops a bit.

Chrono Trigger's time travel works more like crossing timelines that are in parallel but are also in motion, all with some impact on each other. Still a great game in general, though.

It's a bit out there, but Planescape: Torment.

It's not a real time loop, but you're an immortal amnesiac who just woke up on a mortuary slab.
Apparently not for the first time either.

The game revolves around figuring out why you're even immortal, what to do about it, and what your different previous incarnations were up to.
While not a time loop, it has a unique vibe that's vaguely similar to a time loop in a sense.
Maybe more like a death loop I guess (not related to the Deathloop game).
It's a 90s era CRPG if that's your jam.

Probably not what you are looking for but Call of Duty Zombies is a timeloop. Every match you play is canon to the lore. Black Ops 3 on PC is probably the best one to get since it has the most of the maps from earlier games + Steam workshop support for custom maps. Most levels even have ways to beat them and break the timeloop which will provide a cutscene with lore drops.

If you and some friends can get the game on sale the base game alone is great without DLC just for the endless amount of content in the workshop.
