I just got these the other day. Haven't played them yet but hoping to check out Gate later today. I really enjoyed the other Jason Glover games I played so far.
I ordered it. It doesn't seem like a dramatic difference from the main game but enough to get me to pull the trigger. I like legacy games so this was my main reason to get it. My wife and I play Sagrada daily (mostly on mobile) and thought this would be a good addition to our collection.
I'm new to PF2E and GMing as well. We ran the beginner box a few months ago and it is a difficult fight. We had the same problems. The party just wanted to blindly attack the whole fight without any strategy. It wasn't pretty but now they understand how the dying and wounded conditions work.
It's not easy but it's not complicated either. It's a different mindset that needs to be explained.
I think you're cool too.
I work traditional weekends. I usually have a couple of beers and play Pathfinder 2e on Saturdays. On my actual days off I do a lot of chores.
When guests come over who don't normally game this is the gateway game to get started with. Easy to explain and lots of fun.
