We’ll start with INWO Subgenius
I’ll be honest, though I’ve been tracking both Subgenius and Steve Jackson Games since the 1980s, I honestly had no idea there was cross-pollination. Yep, apparently back in the day SJG issued a 100-card deck of Subgenius cards, either playable within the system or standalone. Retail price was $16.95. Full sets on ebay, the few that remain, are in the $400+ range. Now I feel like I must have one.
