I'm enjoying 1.09. There are some Out of Memory Errors after a few hours, but to counter that just set your Autosave to save every turn. There are a few combat issues, but they are manageable.
Something I'm curious about is, and maybe I just haven't gotten far enough yet, where are the flying units like Dragons, Dirigibles, Griffins and such?
I'm also curious to know if there are any thoughts already about an obvious expansion?
