FotG can and must achieve complete movie authenticity by having every ship that is too big for the player to fly move at the speed of plot and/or mission balance.  Best game ever!

Gravity can help with the turning in that instance I guess. And weren't ISDs designed for multirole anyway?

Well while I don't expect an ISD to stop on a dime, there's one bit that's very telling about the ISD's acceleration capabilities in RotJ.

The Imperial fleet is sent to the far side of Endor's moon, and ordered to wait.  The Emperor knew that the rebel fleet was coming, but didn't have any sort of time scale for that.  He simply knew they'd come.  From this we can assume that the fleet was at something approaching a dead stop.

When the rebel fleet arrives, within moments the Imperial fleet swings around the moon and is in engagement range.  While perhaps there was some dramatic editing involved, I can't bring myself to believe that the cut from "It's a trap" to the fleets engaging each other was a timelapse of several hours, so we know that the ISD (And, by extension, the Executor) can accelerate from nearly zero relative velocity to a very high speed within minutes, in order to swing around the moon so quickly.

Actually I just thought about that a while ago, and came up with an alternative explanation, which I think isn't entirely silly:

The fleet wasn't on the other side of the moon, but somewhere on the outskirts of the whole system. The Emperor tells Vader to "send the fleet to the far side of Endor". Did he mean the moon? The whole system? The planet Endor which the moon is supposed to orbit? I don't think it's implausible to think that the fleet in fact wasn't on the opposite side of the moon, but rather somewhere further away, outside immediate sensor range. From there it could have done a short near-instantaneous hyperspace jump to suddenly appear behind the rebel fleet.

You can overthink these things to death and still be right where you started. When they film this stuff they almost never have a table of set specifications for the ships and then think what's possible, they pretty much do what the plot requires and let the fans think about how fast, big, armored, or well armed a ship is. Of course, debating this stuff can be fun so I'm in no means trying to discourage your discussion, just saying, almost any explanation is theoretically possible

Huh, you know, I can actually see how to FRED this.

[chief1983]

Wait are you talking about like how in arcade racing games AI will play catch up and slow down to keep you close by?

[newman]

Axem already did it.

He WOULD have

There are... multiple ways to FRED it, none particularly elegant. :\

[General Battuta]

The way I'm thinking of is the elegant way.

[swashmebuckle]

you most spill the beans

[General Battuta]

I'm gonna talk it over with Axem first.

Well, regardless of accuracy, you will want to make sure they are capable of DECELERATING at a relatively decent speed for the sake of the FS2 engine.

Capital ships coming out of warps in FS2 tend to do so well above their normal max speeds.  In some mods, this becomes really noticable due to some larger custom ships having extremely slow acceleration and deceleration speeds.  Which can result in a large just-out-of-warp ship zooming along at fighter-afterburner speeds, and not slowing down to its normal max speed for a good minute or so.  I am assuming of course that whatever visual changes are being for Star Wars hyperspace to be in FS2's engine doesn't change this core mechanic of course.

Capitals coming out of hyperspace has been sorted out.

Not as clumsy or random, but a more elegant method, from a more civilized time.
