Just wanted to say that i think the ship speed / game speed is fine the way it is!! It makes the ships seem like they are massive ponderous vessels, unlike most other games/tv shows/movies where massive ships zip around like they are made of tin foil...
I read somewhere that you were going to change it... Please don't, I think you just need to tell people about the acceleration feature!
Or better yet include a keyboard list in-game, and people will find it themselves!
