Interesting: with the decreased face-to-face gaming this past year (we did do some: seasonal outside, distanced) I experimented with some AS&SH house-rules (roll-to-cast inspired by Chainmail, random level-gain benefits, random background generation from Through Sunken Lands, etc.), but also resumed work on my CT-inspired Sword & Planet rules. It's been a productive time "gaming", but on the "creative Ref" side, not so much at the table.
