The latest I’ve heard (might have changed) Player rewards are divided into RF rewards (mostly funded by haunts and wearable auctions) and REALM rewards (founded by parcel auctions). What you’re proposing sounds like mixing those together, as mini-games will become more of a REALM thing.
I proposed having a dedicated workgroup for rewards to make suggestions to Pixelcraft. It didn’t spark much discussion, but people generally seemed in favor of it, judging from the poll. Maybe you’d be interested in joining?
There hasn’t been a signal prop on it, because I think it’s important to first establish who’d be in that group before voting on it, and there haven’t been many volunteers yet.
