You absolutely nailed what i was trying to get at in the original post, so thank you. At least i know now that when they find me i'll still have that feeling, even though i'm not actively looking for the next one now.
Collection wise - As long as there's room, and the thrill of the chase is still there, the hobby will always be fun. Maybe when the games room is full, satisfaction of filling it may be enough. Maybe there is some disappointment, as there is no more chasing. I don't actively chase games anymore, I wait for them to find me. But whenever I find one, the excitement returns.
