I have friends with little collector's folders that have the see-through plastic pockets and they're almost full. I routinely hear how they're only 1 or 2 cards away from a complete "legends" or whatever set.
I can't see dedicating that much of my time, money, and soul to such an endeavor. I'll stick to Netrek and hacking DooM and Heretic :)
