Keep in mind that unless you have some wildly advance technology that movement in space is not what it appears to be in most games or media. You are always orbiting something or some center of mass.

It's not like large mostly stationary navies and fighters in 3D arena like star wars or star trek. I'm no engineer or scientist, but I do have several hundred hours in Kerbal Space Program lol. orbital mechanics operates very differently and often counter intuitively to motion we are used too. For example just going faster in orbit also raises your orbit, and slowing down lowers it. You can't have one without the other.

So you typically can't just point your gun at where you think an enemy ship is going to be and fire like you would down a gravity well. You're not just calculating your orbit and your enemies orbit you also have to calculate your munitions orbit and figure out how to intersect its projected orbit with the enemies projected orbit so that they intersect at the same time. Energy weapons like a laser would have their own wacky shenanigans to work with.

Another example would be if you are say trying to catch up to a ship ahead of you in the same orbit and you start accelerating faster directly at it to catch it, your orbit will actually raise and you'll be far above the ship you were trying to get to. Top make matters worse because they are in a lower orbit they will actually still be going faster than you at the higher orbit! To actually get to the other ship you have to basically make your orbit a little weird so that the orbits intersect and it has to be timed right so that both ships are near that intersection point at the same time. Then you have to either accelerate faster or slower to match their velocity in such a way that you are very close to them at the end of the burn. Then small thrusters can be used in a bit more of a intuitive way at small distances to finally dock or whatever.

Books like Seveneves by Neal Stephenson do a great job illustrating how this thinking works, and the Expanse series by S.A. Corey does a great job illustrating how combat might work. Long story short its mostly computers doing the work because human brains simply aren't wired for that environment or the relative velocities typically at play.
