Re: Population research
Tot has been the best government for almost everyone for a while now. Corp doesn't start beating Tot until you end the round on 5000+ roids. If you're just playing a reasonable top 100 planet, ending on 1500 roids or so, Tot is 4.5% better than Corp and 5.3% better than Soc.
(And because numbers are fun: Nat overtakes Tot at 10k+ roids at round end.)
It's really hard to calculate whether playing as Tot all round long is better or worse than starting as Demo and switching to Tot, because with the exception of core mining, research cannot be converted to value.
Corp all round is probably bad, though, now that you need even more research to get your planet started.
"And THEN," Mary was yelling and stomping up and down, "I'm going to take all the tiny little pieces of your body left over from the explosions and I'm going to put them in a bag and then I will throw it in the ocean so SHARKS will eat them! And then do you know what I'll be doing?" he screamed. "I... will... be... LAUGHING." He giggled. "AT YOU!" he added.
