Thanks, folks! I appreciate it very much. :)
I had noticed that this was bundled with the first expansion for only 10 bucks on Steam (much cheaper there than on the GOG summer sale for some reason) so I picked it up and started playing last night. I really like that any items and potions you use are restored in full for the next battle. I tend to horde them but not in this game. So far so good.
Well, I don’t know how I missed knowing about this game the first time around but I’m certainly glad I finally found it. Winner!
