I love the 4e rules, but the Pathfinder campaign setting is one of the best sourcebooks I've read.
Really, it's awkward for me. I worry that I'll get flamed, but I have to say it: I love the work that's coming out of both companies right now. I feel like I'm a part of a silent minority, but I've discovered that I'm really enjoying what both sides are coming up with.
Me too! It sometimes seems a bit awkward being a fan of competing systems, but really, you like what you like. You can like music by different artists, so why should this be any different?
In a way, this goes back to an issue I struggle with, which is that I may like more than one system, and I feel guilty for liking both. That's just silly, really. So in my case, I love multiple editions of D&D, including spinoffs such as Castles & Crusades and Pathfinder.
In effect, WOTC got the rules I need (for learning style and gaming group), while Paizo got the flavour and setting.
Bingo. Two great tastes that taste great together.
My dilemma: is it ethical to hope both sides continue their competition for the hearts and minds of the gaming community, simply because so much amazing material has come out of this?
I think it is ethical to wish both sides success, and hope that their competition in the marketplace leads to higher quality products in the future.
But I love, LOVE hearing that folks are using Paizo stuff in other RPG systems. Every Pathfinder thing that gets converted to 4th edition by fans (or to C&C or Basic D&D or True 20 or Hackmaster or Call of Cthulhu or any other RPG for that matter) increases Pathfinder's awareness, and is a good thing. I'm happy and grateful for all the work the fans are doing in these conversion arenas, since we can't do them ourselves.
You got Pathfinder in my Dragonlance!
What's cool about Pathfinder is that it's not just a set of rules, it's a campaign setting. The setting is a gamer's paradise, giving room for many classic modules to be inserted. It's fresh and vibrant. Plus, some monsters have been reinvented in a way that makes them fresh and vibrant. Pathfinder-style goblins and kobolds are my standard for any game world.
What's cool about WotC is that their 4e rules are sparking my imagination in terms of characters. There are tons of new choices for races and classes, and I'm finding that, for the first time in a while, I haven't played it all.
Both offer tools that can be used in a myriad of settings. Say you want to run a Pathfinder game with 4e rules. Not a problem. Or, say you want to run a Dragonlance game using 4e rules and porting in the kobolds and goblins. Voila, you're done and you have an instant success.
Above all, remember that this is a fun little hobby. You don't owe WotC or Paizo a thing. They have to earn your support. So support that which you like. If you like both, then support both. Take those tools that you enjoy, and go out nad have some fun.
Good gaming!
