My group had mostly been playing Dungeons and Dragons v 3.5 when we first started out. And like any game, you play it enough times you start finding holes in the nuances of the game. Not necessarily flaws, I hesitate to say that, but rather places that because the writers/creators were so deep in the woods, they couldn’t see the trees. (Hey, it happens to all of us, even me! That’s why I have a dev-partner.)
But when the difference in classes (some of it admittedly on my shoulders, I didn’t do as much in-depth research on classes, I just picked something fun to try) started biting us in the butt and making the power balance between players kinda funky. So after a couple campaigns, we decided to try Pathfinder. There was a bit of a learning curve, because not everything is the same, but we quickly fell into using it.
So what are some of the key differences between the two? Like we moved over for, the big thing is classes. Things progress a little faster–you get more feats in general, there are more traits to classes to try and balance them out. They also introduced archetypes and variations, so you don’t have to bounce around and multi-class, take prestige classes, and God knows what else in order to build the type of characters you want. Fighters, rogues, and some of the other fighter based classes got evened out with the sorcerers, clerics, and other magic classes in later levels.
Bad side: prestige classes are basically useless at this point. I haven’t seen a single one that was worth the buy-out for advancing through a prestige rather than continuing into the upper levels of the class I was already in, at least in my current campaigns. (I made a character to deliberately aggrevate one of Ginny’s werewolves who hosts a DnD session.) And if you do need to do a multi-class character, you are screwed, the new system is so messed up. We honestly homeruled it out and said just to use 3.5, because otherwise it’s almost impossible.
What about races? There was a somewhat complicated way of figuring out if a race was playable in 3.5, I rarely messed with it because it was all the eww. I wanted to keep things simple for my own insanity. Pathfinder makes it much easier, helping identify what creatures are possible player characters as well as introducing a bunch of new races to play. I played several outside of my elven standards, and had fun with them all, for different reasons, in different settings.
That being said, some of it seems…random? I remember certain creatures being playable in 3.5 that aren’t available in Pathfinder, I guess to prevent being over powered. But the big one (my silver dragon) wasn’t that powerful with her base classes helping her out, not when you weighed in how much she paid in levels in her class in order to be that race. And some of it is very…weebo. I mean, I enjoyed playing a kitsune, don’t get me wrong, but in combination with a lot of stuff that was added to Pathfinder, it definitely feels like it is catering more to anime, I want to play a ninja/samurai/whathaveyou like out of such-and-such show, rather than the more traditional fantasy crowd of usual Dungeons and Dragons. I don’t mind the representation, I mind that it seems more like catering to a particular fanbase instead of acknowledging another world culture.
What about the worlds in general? Well, general rule of thumb, we tended to play Homebrew worlds for 3.5. I don’t think I even ever learned the “official” canon of the world for 3.5. And while we sometimes headcanon something or adjust a rule to suit our playing styles better, for the most part, we are playing Pathfinder a lot more straight to the actual information in the books. So I can’t really comment on whether the world-building/religion is better or not.
As for mechanics, not a lot has changed, and even if one thing is easier, something else is more difficult. On one hand, yay, there isn’t this ridiculousness of seeing something but you don’t hear it, everything is tied to Perception. On the other hand, I have no idea what this CMB or whatever it’s called is. (Which is bad, I am currently playing a rogue!) So for every step forward, there was a step back in terms of general mechanics. I prefer elements of both…and still hate non-spontaneous spell castors, so really, there wasn’t a huge enough difference for me to reconsider how things work and slate my preference.
So what is the end result? Well, we haven’t fully converted. My solo campaign with the rogue is being run Pathfinder, as is a future campaign with another rogue-variant type. But my silver dragon is being played in a campaign that mixes elements of both 3.5 and Pathfinder together depending on what is easier/suits the character better, which I think is brilliant, though there are obviously still issues. That one is also being run with Greek mythology for the religion, it’s awesome. And as for me… I’m going to look into Dungeons and Dragons v 5 to see if it’s any good for running a short campaign.
