I grew to love Linux because I was hating Windows, I don’t hate Windows because I love Linux. And I don’t want to hate Windows, I wish they were slowly becoming anti-user, but they keep adding (forcing) features that are so unfriendly to the user.
Yes. If Windows was still like Windows XP, I don’t know if I would have ever switched. It used to be fun, not soul sucking.
There’s lots of other reasons I’m glad I switched, of course.
While technically the answer is “no”, people who emphasize the difference don’t apply the “Rule of Cool” as liberally as I did.
I re-used all kinds of D&D 3rd Edition resources while switching to Pathfinder.
Sure, we absolutely shouldn’t just dogmatically use the numbers given in a 3E book with Pathfinder.
But I didn’t find it terribly hard to whip up Pathfinder monster and NPC number adjustments based on my 3E source books, more or less on the fly.
Many numbers given are close enough. Most abilities are easy enough to convert in a way that is fun. The Challenge Rating isn’t tuned as carefully, but i find the usual GM toolkit can address that. For example, throwing in a few extras baddies from over the hilldside can scale an encounter up, and awarding the players various story advantages “for good role playing” can scale an encounter’s challenge down.
If my napkin translation went too badly, I threw “Rule of Cool” at it, and just made sure the players were still having fun.
I will say, I relegated 3E stuff to filler encounters, just as I do with anything else I homebrew.
I don’t mind being on my GM toes for a quick encounter, or a short story arc. But I don’t like having something poorly balanced have a recurring role in my campaigns.
All to say I have used 3E source books liberally in my Pathfinder campaigns, and I’m not sure any of my players have ever noticed.
