A bit off topic I guess, but never an old topic I don't really agree with this, main reason being that the way I see should be produced (as a spurt during a GA) does mitigate the bonus PHI provides. Maybe you can make an academy thanks to PHI, but will that beat FIN for example? Perhaps at bureau and beyond, but not in the early game, which IMO matters more. I'm not sure if that's a popular opinion, but I think I agree with that. Being closer to BW is very powerful and agri is not always necessary. The old opinion was that agri+wheel is the best combo, because they cost the most. I think nowadays the consensus is agri+mining (China!) is the best, which does feel clearly correct to me.
