Two-player trpgs are a weird beast. At their best, there's a kind of tension to them that's hard to describe---and Long Night is definitely two-player rpgs at their best.
Long Night is a structured conversation, with a few prompts and rules to hem it in. The whole thing is centered around a moment of tense calm in the middle of a geopolitical mech saga, and while the players are on the same side, there's *exactly* the kind of built-up animosity between them that you'd expect.
Long Night does a good job with creating and structuring this mood, and mood is 100% of the story that you're telling here, but there were a few places where a specific prompt or term felt just goofy enough that it snapped me out of immersion. "Zebulon-6" for example, or the Mechanic and Pilot's really, really generic callsigns and nicknames had that effect, although they may be less jarring if you play a slightly goofier version of the game, or if you can do 1970s mech drama with a straight face.
There's also a little bit of weirdness with the way the fiction and the rules flow, as the game calls for a repair montage after the two fairly intense dialogues that make up the first 60% of the game, and the dialogues feel like they'd be more natural intercut with the mech repairs.
Finally, the last part of the game goes a bit heavy on making it a romance, whereas the rest of the game is completely okay with it being a story about a heavily tested friendship, and this shift in tone felt like it removed some of the nuance of the situation. I think my inclination here would be to make the game's questions just recommendations, and let the players ask their own questions instead of/in addition to.
Overall, if you've got a friend who likes messy and emotional complexity and fighting robots, I think this has the potential to be an intense, super memorable experience.
For folks who want crunch, or a silly/comedic tone, or I guess a giant campaign or something, it maybe best to wait on this one and possibly check out one of the game's inspirations, Mobile Frame Zero, in the meantime.
I suspect Long Night would also make an excellent performance game (it's even structured like a three-act play,) and I would absolutely recommend anyone doing an actual play podcast to check it out for that reason.
Minor Issues:
-Game page, "has barely escaped from their life from a recent incident", first from should be a 'with'
-Page 4, under Questions, "ours gazes"
-Page 4, under Concluding Questions, "words reach you lips"
