Interesting, thanks for the info. Back in the stone age of RPGs I had everything TSR put out and a few others like Traveller and a few super hero RPGs. My recollection was that adjusting rules to fit your style was just a thing everyone did. Which is why I never saw the appeal for the tournament modules that scored the players for things and doing the ‘correctly’. Hell, trying to run a Champions game from the book would have been impossible unless everyone had photographic memory. That thing was a beast. Not to mention most of the smaller systems having contradicting rules or the absence of rules for what should be common things.
Still…youths!
