I think starting knowledge is fine, especially with the harder difficulties. Otherwise taking the first few planets is a bit of a challenge, especially if you want to grab a Mk3/4 early, as I tend to do sometimes.
8000 for me means I can only unlock 2 mk 2 ships off the bat, then having to wait for the rest of the knowledge to accumulate before grabbing another mk 2 or tech. Other guys go straight for mk2 Command Stations at the start, which aren't too cheap either. The knowledge costs might have only gone up a bit, but they add up at the end of the game.
10000 is balanced with the 500 increase. Drop it to 8000 and you have to take the extra 500 knowledge of 4 more planets to make up for the 2000 drop, unless you feel like knowledge raiding, which is fairly difficult these days.
4 planets= 80 AIP + Time and effort. Too expensive for my liking, especially 80 AIP.
well, we can make it 9000 if you just like mk2 ships and let's see, other defensive structures,
yes you have to take 4 more planets to make it up but first, are you saying you don't unlcok any transports till like, 10th hour in the game? that's 1000 knowledge, especially it's a "must have for all games" i unlock it right away.
then again, your first planet has 500 extra knowledge, you capture another planet, with along the original 2000 knowledge over there, so you can't say 4 planets = 80 aip + time and effort, it should be 4 planets = free 2000 knowledge and no time or effort or aip, of course i may be mistaken because you may not capture 1 planet at all?
So, if we change it to experimental numbers (that's what the beta's for) we have several test values
5000
6000
7000
8000
9000
Given that you already dislike the idea of 8000, we'll rule out 567, now, it's a question of 8000 or 9000
Now, what we want players to unlock , do we want them to unlock 3 mk2 ships, "as you like it since it's easy" or do we want them to unlock balanced things such as turrets, defense structures, or even mk2 engineers. so with that, 2 mk2 ships is the most you should be able to unlock at the start, making it 8000 is perfect, and if they really want a balanced fleet at the beginnning, they will unlock 1 mk2 ship, 1 starship or turret, 1 defensive structure. or maybe just 2 mk2 or 1 mk2 and 1 mk3. So in this case we'll make it 8000. Seeing transports don't need to be unlocked , it's essentially 9000, plus 500, to 9500. then capture 1 more planet you get your 500 back, plus the original 2000.
