For example in Star Wars: Empire at War Darth Vader's 19 km long flagship is in the game, but it is more like 5-8 kilometers long in game.
You can't be seriously bringing EaW, let alone it's Executor, as a good example of anything. First off, EaW has pathfinding issues with anything larger than a VSD-2, and this gets extremely severe with anything Home One sized and larger. The Executor could not move. It simply would spin around, go in fuck all directions, and be not much more than an excellent target for fighters. Unless of course an enemy ship wandered in range or it was jumped right in the middle of an enemy fleet and kept still, which was a momentous task in EaW. On top of that, scaling in EaW was completely non-existent. Look at the scale of starfighters versus any other class, for obvious examples of this.
Star Wars:
Bad guys--> Triangles
Good guys--> Space dicks
And then in the Clone Wars
Good Guys--> Triangles
Bad Guys--> Space dicks
By posting something as ignorant as this you make yourself look foolish. Yes, the entire SD line was very much triangular, even the Acclamator was shaped like an arrowhead. But the CIS and Alliance being shaped like dicks? Are you kidding me? The CIS had prominent ships in the movies, such as the Munificent and the infamous Lucrehulk which were far from being cigarette shaped. The Alliance had barely any cigar shaped ships outside of Home One; the Nebulon-B, CR90, MC80 Liberty, and other MC80 variants don't fit that description.
Stop yelling away the fanbase. They said they disagree but respect the decision. What you love about your logic is that it's dogma.
Or, you know, people could stop beating a dead horse and/or read the FAQ/QnA which happens to answer the "Will the plot device be in" question, which would prevent pointless and idiotic debates such as these. Alternatively people could have listened to logic and realized why the plot device as a ship simply would not work, however we cannot have people be logical, that would be a travesty.
