The fundamental difference in Hx between 1st Ed and 2nd Ed is that in 1st Ed you used to be able to straight up say stuff about other peoples' characters and make it true (like, "You left me bleeding and did nothing for me" or hilariously, "you are my lover"). Now you
ask for people to step up to those roles. 2nd Ed also eliminates the step where you tell other people what your Hx with them is (and they use their options to change that), which means you are doing Hx in a single pass. In many cases, the switch is simply taking the options you had before and keeping them (though asking for volunteers now instead of just naming someone) and coming up with an Hx number that works for "everyone else."
Because of how the Hoarder's Hx is structured, you can't make as direct a port with this approach. But the key point about the Hoarder is, well, the hoard! Hx should be about that. As such, I might suggest something like the following:
Go around again for Hx. On your turn, ask either or both:
• Which one of you have I stolen something from to feed my hoard?
For that character, write Hx+1
• Which one of you once took something from my hoard and never gave it back?
For that character, write Hx+3
For everyone else, write Hx-1. Other peoples' motivations are less immediately materialistic, and this confuses you.
That gets across the essential weirdness of the Hoarder's (generally larcenous) relations with others. It also gives you as the MC the ability to ask all sorts of provocative questions about the circumstances of the above answers during character creation.
