Things that happen in game differently from my headcanon:

• During a dive, destroyers just hang around over player heads
  • Even worse, there’s an actual game mechanic that causes orbital stratagems to have an AoA at 90° at the center of the map but lower it at the edges, like the ships were actually hovering over the center (realistically, all orbital stratagems calls would have roughly the same AoA)
    • I say “even worse”, because I have to actively ignore a decision the devs made for the sake of realism rather than just tell myself “eh, they didn’t think about this too much”
• Orbital stratagem timings make no sense, and are strictly a gameplay balance issue that cannot be realistic: the loading screen shows the first helldiver drops well outside the atmosphere and take several minutes to reach the ground, but turrets take 3 seconds to deploy? This game sucks, literally unplayable
• Surely Eagles must be capable of atmosphereless flight, if the cheap ahh shuttle is?
• At the beginning of the loading screen, the destroyer doesn’t have an atmospheric re-entry fire effect which would be countered by shields or whatever

Things that oddly do make sense:

• Hellpods do have the atmospheric re-entry fire effect immediately after launching, which wouldn’t make sense in the absence of (less than extremely thin) atmosphere
• … that’s it, actually

The reason I made this nerd emoji of a post:
I’ve played KSP and my suspension of disbelief towards games or shows with spaceships is completely broken.
