Very interesting stuff, it's fascinating to see some of the divergences and overlaps between these and things I've been toying with or have cut in past editions (for example, the -1 for injuries is very much an acquired taste. I tested it extensively back in... uh 0.4 I think? Some groups really liked it, but most found it frustrating, so it got cut)
The Navigation check is another I toyed with for a long time, and may resurface specifically as a "Make a Wild Jump" move (which the Explorer's "Boldly Go" supersedes, natch)
Really cool stuff!
