Ever watched a time travel show or movie and thought, “I want to play that”?

Not the 600-page tome, the three-hour prep session, or the mind-numbing dice math—just the story. The twist. The moment where everything changes because you showed up.

Well, welcome to 4-dimensional—a rules-light, story-forward role playing game for renegade time travellers, built for chaos, drama, and jumping headfirst into paradox.

Whether you’re a rogue chrononaut escaping a timeline enforcement agency or an unlucky adventurer caught in a slipstream of cause and effect, 4-dimensional gives you just the crunch you need to dive in, no more and no less.

  • It’s d4 only. Yes, really. Dust off those caltrops.
  • No prep required. You can be playing 5 minutes from now.
  • Flexible character creation. Start with an idea, evolve as you go.
  • Instant adventures. With layered random tables and story seeds, every session feels like the best episode of your favorite sci-fi show.
  • Bend time, pay the price. Mechanics for temporal manipulation and paradox keep the drama flowing—and the consequences close behind.

Designed to be played fast and loose, 4-dimensional embraces the glorious mess of genre fiction: alternate realities, collapsing wormholes, faulty machines, ancient empires, rogue sentient computers, and philosophical debates with your own future self.

Because, let’s be honest—time travel is too much fun to leave to the professionals.

Ready to make a mess of the timeline?
