Tabletop RPG Starter Kit

The big beginner-friendly one (with the free basic rules online) — it is the common language of the hobby, every player knows it, and the published adventures teach the game master the craft. Niche systems are wonderful but harder to find a table for. Start with the popular one; explore the hobby once you have a group.

Runs the world — describes the scene, plays the non-player characters, adjudicates the rules, and improvises the consequences of the players' choices. It is a creative load (prepping and improvising) and the reason a good GM is treasured. Start as a player, then volunteer to GM a one-shot to learn the other side of the screen.

Both. A grid mat and tokens for tactical combat (where position matters); pure description for social and exploration scenes (where it does not). Most groups use the mat for fights and theater-of-the-mind for everything else. The mat and dry-erase markers make the combat legible without the cost of miniatures.

As long as the group wants — a one-shot is a single session, a short arc is 4-8, and an open campaign runs for years (the legendary ones). The magic is the recurring group and the story that builds over time. A regular weekly session for a year creates a campaign the players remember forever; the rule of cool keeps it fun.
