gameplay wise, sure it's annoying. But if you want to argue on realism than the current turn model for Sins is pretty accurate.
- In space, theorically you can turn using sub-engine just like how satelite use rockets to adjust their flypath nowadays. However, while we don't need to rely on inerta or aerodynamic, the Force VS Mass relationship still exist in space. Say a ship has a main engine of 500K Newton and several subengine of about 2k Newton each. Theorically, a ship can make a 180 turns in space while not moving an inch using its sub-engines, but those 2KN engines won't turn the ship as fast as if you have borrow the inertia from using the main engine.
- Now come the question, why don't use multiple sub engine and make a quick turn? I think some of you underestimate gravity, inertia and g-force in space. Sure, space has no gravity, no friction ...etc... but that doesn't mean you can go wild without consequence. It seems people forget that there is a big different between the environment between a ship interior and the vacumm is HUGE. And this difference is actually even more severe than an airplan in the atsmosphere or a ship on water. If it has to compare, it would be more like a submarine at max depth. You guys keep saying space is vacumm, but like I said it seems most forget that the interior of a space ship is NOT a vacumm. For something the size of a space ship to make a hard turn there will probably enough force to either tear the interior apart, or send the crew to medbay. S
Now as far as gameplay goes ... well it's annoying no doubt. For example last night I was fighting in a nebular sector. I have my fleet draw the enemies to one end of the system while I sent a probe to build a starbase on the other end (and lock the phaselane so they can't withdraw). By the time the starbase has its first armorlayer and weapon online my fleet started to fail so I order them to withdraw toward the base. And well, thanks to this wide arc turn I saw my fleet scatter all over the place and I lost a couple capships because they were seperated from their supports. Personally I think the combat model in Sins is a still a bit on the arcadish side to really worry about real physic and well, a mix compromised don't exactly work too well.
