Sure, people who were already wandering into a GW store out of either intent or curiosity in the first place, I'm not entirely sure that counts. The pool of friends and acquaintances I have to try convince all already have their own expensive/time consuming hobbies; PC gaming, game development, brewing beer, 501st Legion cosplayers, car tuning, or other less expensive tabletop games(X-wing, Android: Netrunner, general boardgaming). One chunk of them their eyes practically glaze over as I talk about what I do in my free time, another think it's cool but way too expensive to commit to when they see how much I've spent, and the others are already ex-40k players.
