You can also do this in Space Engineers - steal a ship by jet packing from one to another while in flight, and I honestly don't like it. Jet packs are OP, allowing a player in a jetpack to catch up to a ship in flight, and grinders (think cutting torch) are OP as well, allowing a player to slice into a ship they don't own like Luke slicing into an AT-AT walker with a lightsaber. It makes everyone feel like Iron Man rather than humble pilots of powerful ships. I personally use a mod to nerf this insane jet pack, but most public servers do not.
I have no idea how this works in Star Citizen. I can see using a ship with grapplers to grab onto another ship like pirate ships of old, and then sending a boarding party over. This plays out both in real life and many sci-fi movies very realistically. Heck, it's the opening scene of the most famous sci-fi movie of them all, the original Star Wars. It's more practically with larger, slower ships than two fighters, though I can almost picture Tom Cruise popping the hatch on his F16 in Top Gun and jumping onto the MiG below him and tossing out it's pilot, but that's because I've watched too many Mission Impossible movies, LOL.
