I'm actually really curious why you think Justinian's land is so bad. IMO he has a lot higher land quality than lost leaders this game, although Peter's bananas start is obviously better. Qin's land seems kinda on the poor side to me and there's a good chance his shot at winning gets tanked due to Peter or Alex attacking him before he has a competent sized metal army. Is it just his fish start? Coastal spread from Justinian to Peter WOULD fit my feel of the game...
EDIT, Game Seven Spoilers:
Justinian's territory didn't end up a problem, but everything else was spot on Wyatan (I DID also say I thought Alex could snowball). Great work, Wyatan!
