And yeah keith, I might be slightly exaggerating the amount of stuff I need to build before I can do anything. Sometimes though, I cant really find the time to mess around in wormholes (because either there arent enough immediately available, they just dont take long enough).
If I dont own any planets that arent my homeworld, non-mk1 systems wont go on alert. the jump from guardianless mk1 systems to guardians on mk2 systems is actually kinda huge by itself, and I dont really like making that jump until I am ready.
In some cases, like if I am on the inside of a concentric circles map or something silly, I can pick up systems that are directly defended by my homeworld's defense, which is perfectly fine. But until I can make these segments that are 100% safe, I feel it is rarely worth taking space. I am not really sure if it is just because the broodlord/infestor fleet is just too slow to deal with the counterattacks of a ling/muta army, or because I just dont like loosing things..
And martyn - I need about 200 turrets on a planet before I decide its reasonably safe. This number is sadly not exaggerated at all. Unfortunately, I can do that with about two planets early on, even if you ignore the resource cost..
I am thinking like I mentioned somewhere else, I should run a game with inflated difficulty hybrids and spire plot, with the tradeoff of 0 waves. The only potential issue I can see with that is that it would cause a huge jump in ai response at the first spire city compared to pretty much the entire rest of the game..
It could probably still work though.
