Time Wizards
Time Wizards or LOS MAGOS DEL TIEMPOOOOOOOOO is a silly and chaotic rules-lite homebrew. It first surfaced on /tg/ in the writings of a tripfag named "DM Kroft." Anons laughed, said "man, that sounds like a hell of a lot of fun," and screencapped his posts. Many wanted to play the game, and it was spoken in hushed whispers that maybe Kroft would post the rules, but nothing came of it for quite some time.
Shit gets done
Some odd number of months later, anons reverse-engineered some rough rules for Time Wizards from DM Kroft's descriptions, making flowcharts of gameplay. On October 14, 2013, an anon posted a proper rulebook, and the fa/tg/uys saw that it was good.
The rulebook's in 1E currently, so if you play it with your friends, post results!
The Lawrence Incident
In early November, 2013, Time Wizard Lawrence storytimed his glorious experience playing Magos del Tiempo. Not once, but twice. DM Kroft himself was in the thread, and POSTED THE ORIGINAL RULES. He says they should not override or invalidate the reverse-engineered rules. In fact, there may be an effort to create a hybrid rules set... And then /tg/ delivered those rules too, with cards.
