Once I get the urge to buy, its a matter of what I liked playing or reading about since the last purchase and getting the first decent specimen of the game. ToM was an impulse buy, tz, rfm, swep1, and fh were wants and spacey and embryon were opportunities that came up when not in the market for a game. But yes, no matter how long or short the hunt was, its always great fun. Longest search say a month or two
