Ramming in space is silly- these are spaceships, not triremes.
I seem to recall a specific instance of an ISD collision in the movies.
If you don't like it, think of it as boarding actions or something then.
Ah, the ultimate example of getting too focused on your target that you don't notice anything else: "Chase the Millennium Falcon, we can catch it!... Whoops, it has decided to remember space is 3d and gone down... Oh, ****, where did that other mile long spaceship suddenly come from!?!"
Really, what were the crew doing on those ships? What was the plan? Why did they seem to think that the fact that the Millennium Falcon was between them meant that the fact they were going straight for each other didn't matter?"
In the Empire Strikes Back the ISD's don't actually collide.
Star Wars is a cinematic fantasy. How cinematic would it be for a CR90 and an ISD to be going towards each other and then just sit in the same spot in space just bouncing off each other?
Better yet how would it look on the screen if a MC80 and a ISD to just sit there bouncing off each other like a couple of Goodyear blimps?
The worst thing I don't like about the ramming rules is that I actually use them as a viable tactic to finish off a ship. It's just too tempting and addictive ☹️
I've said before that I don't like the ramming rules but I've also said I'm willing to accept them because they are better than the alternative but I would prefer the ships to scrape down each other's side.
