Ascending Empires might be ‘the one that got away’ for me. At that point I just didn’t understand that non-mainstream board games get really limited print runs and are quite likely to never be reprinted. I got to play it once, loved it, and still feel like it was an amazing combination of gameplay elements; but I didn’t buy a copy when I had the chance, and it’s been out of print ever since. Supposedly a 2nd edition is in the works, but that discussion dates back a couple of years and there’s still nothing concrete; so, if it’s still on the cards at all, I presume it’s not a current focus.
