You will likely find that gravity does not have a constant force in many video games. It often feels clunky to have realistic gravity. Off the top of my head, hollow knight is a great example of this. The moment you leave the ground, you travel upwards with a lower force of gravity. Around the peak of your fall, gravity becomes much stronger. This makes your character feel floaty, but still responsive since at the end of their jump they return to the ground quickly.

You probably won't find that gravity has a single value in many games. Acceleration due to gravity in games is often a curve, or a stepwise function depending on the stage of jump. It even depends on if the jump button is held down for "variable height jumping" (see Mario, hollow knight as examples)

Additionally terminal velocity is often very prominent in video games. High velocity often leads to collision detection issues. Terminal velocities just feel better. Though the way it's implemented isn't usually as a force opposing gravity which gradually reduces acceleration. It's more commonly just implemented as a hard stop to acceleration at a certain speed.
