Trying to crowdsource your next Isekai, huh?

Die, probably.

Go on Slack and say I’m going to miss the daily stand-up.

First thing, try and breathe to see if the unknown new world has an atmosphere compatible with the one I'm accustomed to. If not, I guess I'm dead.

Second thing, determine if I'm in a wasteland / nature setting, or a civilized one.

Third, regardless of the answer to the second, take stock of my current resources and seek new ones. Water is highest priority, food second, shelter third.

what are you talking about that's literally already how underground trains already work

See how much insulin I have left in my pump and start preparing myself mentally for death.

Wake up, Mr. Freeman. Wake up and… smell the ashes.

Hey you, you're finally awake.

I'd seriously worry about not having immunity to whatever diseases exist in that world, and the people of that new world not having immunity to whatever I might be carrying from my world.

Probably try and figure what the skills of the other survivors on the train to assemble a team with the goal of survival and information gathering.

I would be shocked for sure but how would I know how to react if I don't know what this new world is like? Does it look like a barren wasteland? Does it look like Dinotopia? Does it look like a different planet altogether? When you say 'unknown', is it unknown to me only or do you mean it's completely devoid of any civilized/intelligent species?

Pending Train is pretty darn close to what you're describing. I only got through the first episode, it falls prey to a lot of annoying little tropes, but it's a cool concept for sure.

Check for my super cheat powers and pick the first woman for my isekai harem.

I'm thinking odds are it's either a busty elf or a cat girl 😜

Well I mean first off if everyone on the train was there you would want to discuss how to procede given the unknown part. I think the one person has it right in that I can't think of something like it before narnia.

1, get really annoyed that whatever plans I had are now changed because I'm not super good at paradigm shifts.

2, try to make the best of it because I really believe we bring our own good time.

Check if wifi/mobiledata still works.

Probably just sit and wait for what happens next and hope all the people around me don't freak out.

I lived in Japan for years without knowing about the whole isekai thing; I've just never really been into anime/manga.

Stay the hell on the train. Observe what happens to other passengers when they get curious.

Assuming I survived in fairly good health?

Observe. No details would make me skittish with this

Here's some educational material for anyone curious. https://www.youtube.com/watch?v=CbRxeJXpNOE

Fight the urge to immediately get off the train.

Even with as many episodes of Star Trek as I've seen, I'm sure I'd want to rush right out and start exploring.

I’d hope this one is better than what’s in the rear view mirror.

Also, happy cake day!

I'd shit myself.

I would be quite surprised

Have you played Kult because it looks like the thing which can happen in that game

Immediately gather any crumbs.

Find the author of the isekai that had made it happen and punch them in the taint

Freak out. After that, it would depend on which world.
