Current plan is still to do cards. I'm trying to use Scrivner to organize everything. Turns out when you're trying to organize a shit-ton of fucking decks, combined with hundreds of cards, Google Docs isn't adequate.
But I've thought of ways to simplify card making, since I'm no longer doing a distribution model.
I have, however, decided that I'm most likely doing to use something similar to the +cookie system that people are familiar with, to chart progress in a fair way. Which means that everyone gets cards and such when they hit a particular milestone, and it's not just staff arbitrarily deciding when you can have something.
Which means that despite not really doing a traditional progression system, Krillin can still end up the savior of the universe, which is the most important part of my vision.
Addendum: I intend to make my card thing open source, just as an FYI, so that people can do whatever with it.
