I don't see how what I'm saying here is so complicated? If it takes 350 turns to fully explore an ideology tree and Hiawatha launches his spaceship in 250 then you didn't even get close to getting to use the new feature and a situation like that would make all the improvements in this expansion for naught. That's all I'm trying to say here.
We haven't seen how we actually get tenets yet, so it might be a bit premature to say things like that. Still though, you're completely right; I was utterly unaware of the state of Standard speed. T300 Info Era? I don't even know how you'd play that. Probably have the whole game done in a few hours.
