Limited Print. Limited Time.

Guillman’s Guide to Speed was created for Kickstarter — and we didn’t print thousands of extras. What’s available now is all that’s left.

Once these copies are gone, they’re gone.

Finally, Rules That Keep Up

Fast-paced games deserve fast-paced rules. GGtS ditches slow systems and convoluted mechanics in favor of something better: bold mechanics & snappy systems.

Everything’s built for intuitive 5E gameplay, whether you’re running a street race or a full-speed dungeon escape.

Playtested by dozens of tables. Balanced for speed.
