Damm I've been wanting to start a new tactical high fantasy campaign, too, but this won't be out for a long while. Will probably go with Pathfinder 2E or finally satiate my curiosity about DnD 4th edition, and will be looking at this again in a year or two.
Still, I've been enjoying their latest releases, and I'm always tempted to fund a Matt Coville Kickstarter just so he keeps making videos lol.
If anyone on the fediverse playtests this, let me know how it looks!
