8 out of 10 planets, just WOW, mind blowing, you fight ai homeworld immediately with tons of resources with at least 1, at most 16 wormholes to defend. great idea,
Spokes is the best, as you'd want the planet that connect to every other. 2 wormholes to defend against very low progress AIs.
Yes, you assault the AI homeworld on the first go, and it is alerted, but you have 8 special unit ships with 8 times the normal shipcap (each!) So you get 3 (base) + 8 (special) = 11 * 8 = 88 times the normal starting ship cap. And then you have Knowledge, which is actually reduced (compared to 8 players). 2500 per planet * 8 = 20000 + 10000 (initial) = 30,000 knowledge. Riots, Zenith Spires, MRS, and bascially any 4 ships you want to have at Mk3 (haven't done the math on that though, but 30k knowledge is a lot).
