Congratulations, that is no small feat! Got it in you to tell us about it? I love hearing campaign stories

I use LogSeq to organise all my notes. My group meets in-person, but I use Foundry to put background art, NPC portraits, etc. up on a screen, as well as to manage any NPC character sheets.

It may stretch the definition of 'tool' a bit, but the other thing I do is set up my laptop with four desktops/workspaces (notes, Foundry, music, rules) so I can switch between them with Ctrl+Windows+Left/Right. It's a minor thing, but I am constantly surprised by how many people I run into who don't know that you can do it. Switching desktops feels like much less friction to me than Alt+Tabbing between windows for some reason.

Outer Wilds. Endings of both the main game and the DLC can still get me to tear up a bit. I saw a post somewhere, don't remember, that said something along the lines of "Listening to the Outer Wilds OST is the only way I feel my feelings any more." It's about like that.

Seconding Fate, the rules do a good job of supporting the fiction rather than encumbering it. I felt it very much supported that feeling of "I can do anything I can reasonably imagine."

To help with the tyranny of the blank page, I'd recommend coming up with a pregenerated character to demo how it all works. Then, encourage her to change or adjust anything she wants to on the sheet. My players initially found it easier to modify something to their liking than to come up with something from scratch.

Magic can be as simple as "Roll your Lore skill" if you want or you can look up several more detailed add-ons that are out there, like Fate High Fantasy magic.

The rules are freely available here: https://fate-srd.com/fate-condensed.

I have put hundreds of hours into RoR2 on PC, love the game. I recently purchased a Switch copy so I could play with a friend of mine who is console-only. Sadly, the port is still in a pretty bad place when I checked last (2-3 weeks ago).

I am not expecting the PC and console experience to be identical by any stretch, but I am talking about basic issues like the music on each stage cutting out after playing for only 10-15 seconds, wonky damage (Beetle Queens absolutely massacring us even on Rainstorm if we touched their projectile splash zones), and all the other miscellaneous issues from the patch like logbook being glitches, unlocks being unpredictable, etc.

I think it could potentially be fixed, but I would give them time to put out a few more bugfix patches before I considered a console purchase

I have not yet played Return of the Obra Dinn, but it is always high up on the list when I look for games like Outer Wilds. I'm a huge fan of Outer Wilds, so maybe the recommendation can work in reverse

From what I have heard, the deduction is not as intense as in Obra Dinn, but there is very little hand holding, and the whole game has been brilliantly designed so that it is driven entirely by your natural human curiosity. Once you get through the initial "tutorial" section (probably the roughest part of the game, push through!) the whole game is wide open. See something weird orbiting a distant planet? You can go straight there and start poking around. If you follow the leads that turn up there, you will eventually even figure out what it is, and why it is there. Do that enough and you'll eventually figure out the strange mystery of your home solar system.

Can't recommend it highly enough, but you only get to play it without knowing the secrets once, so go in as blind as you can. It took me 20-30 hours to "solve" the main game, maybe another 20 for the DLC, which is also well worth it

Man, we ended up setting up a wiki for all the ones from my last campaign... it's down at the moment, but here are a few I have saved on my phone:

"My companions and I are professional adventurers"

"Some of us more professional than others..."

"For no sexy reason, what does the pope look like?"

"Also, I'm not doing terrible! But I definitely just got stabbed."

Bard: "No, this is wholesome [Bard] moment! Anyway, how much money do you have?"

Sorcerer: "[Ranger], we are about to do some wacky-ass magic"

Ranger: "In that case, I would like to watch it from over there."

Sorcerer: "I will not be doing it. I will be joining you."

GM: "Divine and wild magic start pouring into and it's like... Have you ever licked a battery?"

GM: "Divine, chaos, and dragon magic flows through you—"

Bard: "And bardic from the inspiration!"

Ranger: "Oh I can add some ranger nature!"

Sorcerer: "And I have one that can help! I cast minor illusion to make a "do not disturb" sign."

"If I take one more step, it'll be the furthest I've ever been from home..."

"You didn't even have to step."

"If I take one more interdimensional vortex..."

"Your left or my left? You're an orb."

"I am."

"Float like a flowerpot, sting like a school bus."

That is exactly what I ended up doing! It was a blast, definitely would also recommend

Outer Wilds

If you're a naturally curious person, the odds are you will probably enjoy Outer Wilds. No other game I've played has ever had quite the same blend of mystery, conquering the unknown, and semi-realistic space exploration.

Could someone make another game like it? Not impossible, I suppose, but I think you would be hard pressed.

Should you keep playing the original? You really can't, one time through is all you get. Once you have discovered all the secrets and uncovered the mysteries, that is your journey through it. Still fun to visit every once in a while, though

The Chaos

Seconded! OP, in a similar vein as the world building games you already mentioned, you might find Intrepid interesting. I could see it being used to do world building + history of some of the major players and nations therein.

I could also imagine the relationship map it uses being hacked a bit to allow for some Disco Elysium style personality skills / thought cabinet shenanigans if you were interested in leaning into that in particular.

I think you've received lots of great advice here already. One additional thing you may want to keep in mind as you're weighing your options is how the manner in which this character exits may impact other players.

Obviously, the needs of this player come first, and making whatever changes they need to ensure they can keep having fun in the game is most important. But I bring it up because, in a similar situation where I was running a game for a player who wanted to switch characters, I executed the change in a bit of a clumsy way that one of my other players found frustrating.

I had worked together with the player who wanted to change to craft a heroic last stand scenario in which their old character would sacrifice himself to allow the rest of the party to escape. Critically, we didn't discuss these intentions with anyone else at the table. One of my other players picked up on what was happening the moment we started playing it out, and did everything he could to prevent the loss of a party member. I essentially railroaded right over anything they tried.

Afterwards, they told me that while they understood why I ran it that way once the other player had a chance to explain their intentions and new character, it still wasn't very much fun to play through in the moment.

All this to say, if I had to do it again, I would make sure I have some sort of buy-in from the other players. They wouldn't need to know all the details, certainly, but I think a little heads-up would have made that experience much smoother for everyone.
