Well, my philosophy is that Pathfinder adventures are first and foremost entertainments, and so when I am GM'ing or playing it's my job to damn well entertain the table -- even if it means killing them! (Luckily that's rare.) Every group of players I have GM'd is a little different. Some players like crunchy combats and the chance to deploy sneaky tactics. Other tables like method acting their character, running cunning diplomacy and dastardly deceptions. Most tables are a mix. I try to bend the adventures around to satisfy the assembled company, whoever they are. They usually humour me when I do silly voices and crappy accents. Some of them are kind enough to put me straight on the rules and stuff like adding two and two.
I love to play, as much as I love to GM, and I have learned a lesson from every GM who has run a game for me. We are lucky enough to have some brilliant GMs in our Pathfinder community.
With Dave Harrison, Chris Brockley-Blatt, Carol Tierney and Ian Hawthorne, I help run the PaizoCon UK event and every year we aim to make it better. We don't always succeed, but with the forebearance of our lovely players and GMs we reckon everyone has a good time. Do come and join us if you haven't yet tried it.
2017 was great for the growth in local groups. My resolution for 2018 is to continue to focus on the London area to create more open places for players in PFS and also in Adventure Paths and Modules.
