Does anyone have a simple formula yet? I just need something in the ball park. Without further guidance, I plan on going with a level 5 PF1 treasure horde of 1000 gp = a level 5 PF2 treasure horde of 1000 sp?!?!?
Trust me, I wish it were that simple, but tons of things don't even come close to that conversion rate, see for yourself e.g. Chain mail PF1 150 gp, PF2 6 gp.
Chainmail in PF1 was pretty mediocre. Even if it had cost 60gp instead of 150gp, I don't think it would have been popular. 90gp/9gp isn't a big deal for 95% of your adventuring life.
It's really only the big expensive magic items where the differences could matter.
