Did you pick up the solo Sellswords and Spellslingers? $8 for the rules and ten scenarios. Character progression. Same designer as SOBH.
What's interesting (and chaotic!) is that, instead of setting up your opponent's forces and using AI, the event cards just spawn them semi-randomly, as well as from behind a bush or tree near your characters! A bear popped out of a bush and nearly eviscerated by wizard that way!

I think this is a good solo mechanic, as it prevents the player from the usual outguessing an AI that sets up on the other side of the board. OTOH, It's random and brutal! (: I might use LOS and a direction die and/or unrevealed markers if I get around to ripping off S&S's ideas. (:
You can finish a scenario quickly, so I finished it in a week. Reviews say you need many multiples of a single type of miniature, but I didn't particularly run into that problem. For some reason, the scenarios *aren't* ordered by difficulty, so review the intros to make sure you play from Easy to Hard. Fireball is OP and you want to cap how much you can modify the activation roll or you'll get too many turns and the bad guys not enough for a challenge.
