There's a post about using it for Swords and Wizardry here:
http://d20darkages.blogspot.com/2013/04/dcc-rpgs-funneling-system-for-swords.htmlI think a distinction between LL as a funnel and the DCC funnel system is mostly psychological: The character you roll-up in LL is your character and you invest time on background and equipment, etc while the DCC method is starting people off with the concept that your characters will die, most likely sooner rather than later, and don't invest too much in them yet. I played an LL game where a player quit because his character got aced by a raider's arrow in the first shot of the first battle. He had come up with this great new character and it's dead before a single action in battle (we had lost initiative). If he had gone into it with the idea that his characters would die like that, I think he might have stayed on. (As an aside, we were able to convince him to rejoin later and he was a great player for the group. His first question was, "You aren't going to kill my character in the first round, are you?")
DCC is the first fantasy RPG to really capture my attention since ADD1e/B/X (and LL/AEC, the best retro-clone IMO) but the funnel isn't the big draw for me: I'd like to try out that magic system and crit/fumble system. And the new dice are cool. (And before you complain about new dice, remember that that was a
huge complaint about D&D back in the day, a complaint that went away when d20s, d12s, d10s, etc became more widely available.)
