What?
14/21?
A mere 2/3s?
401 is much, much worse than that, lijacote. It's 19/24. Based on current throne holdings, I could in theory get away with defeating a measly 2 of my remaining 4 rivals, but yeah, effectively any of us wanting to win is going to have to beat all comers. If it was just 14 points to win, I could squeak through by finishing off the squid, backstabbing Mictlan, and trying to hold the ocean like a thin blue line while ignoring the north's existence. As it stands, there's not going to be a throne victory without a fullscale invasion of the north by the south, or vice-versa - and realistically at least two more nations (to include one or both of Argatha and Scelaria) will need to be wiped off the map to securely hold enough turf to make any throne win happen. Probably three more.
A 75% victory condition - or even an 80% like 401 has - might not sound like a lot on paper - after all, it could be achieved with as few as 2/3s the thrones - but realistically, to get a nation strong enough to capture, claim, and hold that many thrones you basically need to be able to seriously overpower all the other nations. I'd say 2/3s of the points might a reasonable amount for us to use, but that's as high as I'd advise. 12/6/3 at 2/3s would be something like 22/33 - if you were lucky, you could get that with 10/21 thrones, and worst-case it's 17/21. More realistically, it'd probably be around 14/21. That'd probably mean one team dead, and one or two more on the defensive.
