First things first:
Gameplay is fast paced, fun, though.
Graphics and detail are amazing.
The first new space superiority ship you have access to (Hestia) seems to not appear in the shield gauge. The gauge itself shows, but not the ship inside the gauge, like the FS2/1.
Sometimes my teammates appear to not have shields. Maybe they do, but when targeted, they don't appear to have shields on the enemy shield gauge.
Other things. Language has been mentioned. I guess I've gotten used to playing older campaigns, but hearing Microsoft Anna swear caught me off guard. Granted, if I wanted, I could edit that out using fred, yet, still, I wish I didn't have to. From reading some of the other posts, I *really* wish I didn't have to.
Grammer. As was mentioned, get a native speaker.
Edited to add Hestia name.
