I don't really like the idea of limiting OB. I mean, what's the point? Economy "is" still an important part of the game. We just want less focus on it, right? I mean otherwise, we may as well just skip explo phase, randomly allocate planets to everyone and give them prebuilt 300% plaents with infra. That way people can get into the fighting straight away..
No, but, it "is" nice when a coordinated fam, with good strategising can gain superior advantage through Eco - it's just we need a less focus on it - not to get rid of it completely. Also, being eco focused, is still viable part of the game (we still want bankers to compete with each other, make money, produce resources etc - not everyone likes to attack).
Like I said, I think we just need to shift the focus away from it. Ie, make it less dependent on the success of your fam.
Perhaps increase OB% costs (e.g. reduce planet sizes by half). That way it's going to get really expensive to OB really quickly. Don't know, I'm sure there are other ideas! Another one could be (don't know, just thinking out loud), that regardless of individual networths, if a small fam takes a planet off a bigger fam, they always keep the infra. Whereas if a big fam takes off a small fam, they lose it. This way small fams attacking bigger fams (even if they jump an attacker big to do so), will have a jump start in consolidating allt he planet gains - assuming they keep them).
Altruist, will reply to your post later.
