Hi, i've started to play beta 4 only couple of days ago so not much at the moment but still couple of things:
1. Sci-fi-wise, i guess it's unlikely that any star empire would upgrade their frigates, cruisers, and battleships, but forget of upgrading their fighters, don't you think?
2. Also i guess alot of gamers would not only like to see their empire grow size and might-wise, but also would like to see their new technologies be represented visually, couple new turret-ports, or shield lights changes appear after new tech research would be sooooooo nice to see!!! This is also valid for planet developement and battleship level-ups.

)))
3. More random events please...pirates don't last long, you know!

Here is a couple ideas....wander-in higly advanced alien space-ship with strange techs onboard which you can research if only you could defeat (or maybe even befriend) it!
Space creatures!!!! Wandering asteroids(lost space stations of unknown origin in long forgoten and seemengly empty sectors(found only by scouts with special eqipment for example)) - capture them and use for your own good! Maybe even large space objects(dead planets or stars passing by and brinig wealth or destruction). Solar flares!!! Bursts of space radiation! (These would force you to look more cearfully after you planet defence upgrades in early part of the game).
More to come, thank you for listening!
P.S. Anyone thought that normally spaceships in this kind of thechnological level sci-fi books have manuvering thrusters? Err...like those of Starfury fighters in Babylon 5 or lets remember Larry Niven "Moshkits" dilogy...

Visually watching ships using manuvering thrusters would be so awesome! Oh yesssss!!!
