I disliked D&D Next. I never even tried the Next Adventures (Ghosts of Dragonspear Castle?) I didn't like HotDQ when it came out. For me, it didn't start to click until Lost Mines of Phandelver.
All I can say is that I didn't like the Pathfinder 2E Playtest. I want more information before making a decision about purchasing the full rules. I'm at a "soft pass" currently.
I think you I just agreed with me. In 5 years time you’ll barely remember this playtest.
