Showed my brother who's visiting over christmas the latest GC2 build and he pointed out a nice little thing.
The number of troops (on a transport/colony ship and even the invasion screen) could be better expressed by either adding "000" onto the end (i.e a troop ship with 500,000 troops.) or adding a K to express the same thing (500k). this moves the system away from the more abstract numbers without causing any change in the game mechanics.
At the moment when you look at a transport or colony ship a new comer first thinks it holds a mere 500 soldiers to invade an entire planet. It actually means 500 thousand (or was was it million? my poor brain!) soldiers but it looks a little strange. If it was more clearly defined it could subtly add quite a lot to the atmosphere of the game and appear more believable.
