Exactly this. While 5E is my favourite flavour of D&D, it's getting a bit stale. I've never played PF1, but PF2 has enough interesting things (the 3-action economy, crit success and failure, tactically diverse monster design, cool death and dying rules) that I'm willing to give it a try for a campaign. I doubt I'll create my own adventures, but this will also give me a chance to try a Paizo adventure path - I haven't been impressed with the 5E campaign books so far.I never played PF1, but I'm currently running 5e, and will probably add PF2 as a secondary game. Whether I will ultimately stick with one or the other is too early to tell. I'm a little tired of the simplicity of 5e, but I'm hoping PF2 doesn't go overly complex.
I agree except for the last bit! I loved Lost Mine of Phandelver (running it a second time now), Princes of the Apocalypse and Tomb of Annihilation (although it's looking like we won't be able to finish that campaign, sadly, but roughly 70% of it). The latter two are rather difficult to run and I would not recommend them for starting DMs though. I haven't done any of the others, but Curse of Strahd is often regarded as the best of the bunch.I haven't been impressed with the 5E campaign books so far.
