Enemy ships in your game react in a way that is very plausible if it where real life... and for that I say bravo, but it's not fun- again, just my little opinion.
Perhaps the current AI and controls don't let you appreciate the newtonian dogfighting experience. That's why I'm all in favour of manual navigation (the option of it). If you were able to perform more newtonian maneuvers, and if the AI did so too, with some sensible tactics (and not the ever so predictable ones it's using now), perhaps newtonian movement would be even more fun than fictional movement.
Imagine such a dogfight in a dense asteroid field. And I'm talking about asteroids which are still (not moving). Yet, avoiding them is no easy task. You should try making PR's asteroid fiels a little denser, with smaller asteroids (or at least greater size variety, like where WCU is going), and make them still. Try dogfighting in there. Fictional movement makes it real easy to dodge the (still) asteroids, but newtonian movement is another issue. You have to break, plan your maneuvers. You can't just face the target to go guns blazing because, if you do so, you don't see where you're going to (you still move in the same direction you were moving a few moments ago, since you're thrusters aren't that powerful). And that adds to the challenge, and the fun.
I remember a Freelancer mod that accomplished that... I think it was the rebalance mod. It was anything but perfect, but made me realize how fun can newtonian dogfighting be.
Add real collision damage to the mix, and you're set. There's real adrenaline flowing, since if you hit an asteroid, you're history. You can't afford hitting an asteroid, so you're senses fire up, alert at the possibility, ready to dodge any incoming asteroid. It's real fun.
