As someone heavily invested in PFS, I am rather saddened by the move to 2E. So far I have only liked maybe 20% of what I have seen them post for 2E, and unless there is some MAJOR design changes during the playtest, I currently have zero interest in ever converting over to 2E.
So far I've liked everything I've seen in the blogs and plan on going all in unless they make a bunch of major design changes. I don't think they're going to do that though. I think they are going to fine tune the system they have and make minor changes where necessary so that they have a solid foundation on which to build the next 10 years of Pathfinder.
I plan on buying the last few books of the current edition and then starting fresh with Pathfinder 2E. I love how they've grown Pathfinder over the last 10 years but Pathfinder was a patch for a game system that was showing it's age when Pathfinder was born 10 years ago. I'm not surprised that they waited until the 10 year anniversary to make a solid break and move forward with Paizo's vision of what a game system could be. It's not too hard to see where Pathfinder 1E's limitations, inherited from 3.X, are becoming noticeably difficult to design around. It is simply time to start from scratch and build a new system that takes into account not only 20 years of 3.X and Pathfinder but 20 years of game design in general.
I still have dozens of characters that I'd like to run in Pathfinder right now. I still have years to do so. I have at least 2 years of Pathfinder campaigns to run before I'll need new material. I'm going to use that time to learn the new system by participating in Pathfinder Society. I really like the idea of starting at ground floor and working my way up. I wasn't able to do that with Pathfinder 1E.
I was going to port most of the Pathfinder classes over to Starfinder since that ruleset resolves most of the issues that I had with Pathfinder. I was going to make it my go to rule system for everything. I've changed my mind now that Pathfinder 2E is coming. I've decided to let Starfinder be Starfinder. There's no need to saddle it with Pathfinder's baggage when I can use it to explore new concepts within Starfinder's own paradigm.
I'm going to buy Book of the Damned, Ultimate Wilderness and Planar Adventures to round out my hardback collection. Those hardbacks will always have a place on my limited shelf space. I'll finish grabbing a few PDFs and physical copies of the things I like the most while I wait for Second Edition to start.
I'm looking forward to Pathfinder Second Edition and I'll have Pathfinder First Edition for many more years.
Unless Paizo send ninjas to destroy the physical and digital copies of all the stuff I've bought over the last ten years. If that is a thing that happens then...
