These rules work very well at their intended use. You can quickly create a handful of characters for each player. For those not familiar with DCC and its funnel system, the setup of is to give each player mutliple weak characters, most of who will die horribly - hopefully a few will become heroes. The zero level characters are much simpler than 1st level characters under the assumption that most of them will not live long enough to need a detailed background. The idea is that a characters personality will be found by their actions in play.

I have run a home brew funnel adventure with these rules and the rules functioned exactly as intended. If you like the idea, this publisher also published the fun funnel adventure Tournament of Pigs which has a 5e version.

I kickstarted the physical box for Tournament of Pigs and ran it for the first time today. One of the best one-shots I've ever run, including 2 new to DCC and 2 players new to roleplaying games in general. Have other products from WW and they are all high-quality.
