Think of the relationship between "optimism", "pessimism" and "realism":
generally, those words are respectively interpreted as "focusing on the good things", "focusing on the bad things" and "ignoring (or trying to ignore) personal biases on the topic at hand".
In a way that makes sense, the universe defines our perception on things, not the other way around.

However, let's suppose you just had a reality check, at least as my terminally online ass knows the term as.
That means something happened to you, that forced you to realize something about yourself - be it your body, your psyche, your knowledge about anything. A realization so undeniable, that, despite your lizard brain's psychological self-defense mechanisms' censorship attempts, made you realize you've been wrong about something.

The reality check brings your mood down in the short term, and possibly pushes you to improve yourself (or, alternatively, to [concoct a workaround to the tyrannical laws of the universe]) in the long run, but... that's not truly neutral, is it?
It may be a "bad" feeling possibly followed by a good outcome (see: cognitive dissonance), but it is never a GOOD feeling followed by a possibly bad outcome. The latter case is a confimation bias, if anything - the opposite of a reality check.

Going back to the first paragraph: if someone says "I'm not a pessimist, I'm a realist" you may conflate that person for an pessimist, but not an optimist.

The single game I "played" on Windows was Helldivers 2, when I Steam Family'd it from a friend before trying it out through Proton.

The HELLDIVERS™^©®^³ 2 EULA is a god damn URL

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.

(The "Windows" slices of the pies are entirely made up by Baldur's Gate 3, which also runs well over Linux)
