What RPG feels like D&D but is simpler?

Identify which part of D&D is slowing your table down

When a group says D&D has become too complicated, different people at the table usually mean different things. For a player, complexity often means an eight-page character sheet crowded with situational bonus actions, spell slot trackers, feats, and subclass triggers that require constant cross-referencing. For a Game Master, complexity means multi-hour session preparation, balancing encounter budgets with monster Challenge Ratings, and memorising condition rules across three hardcover manuals.

For the table as a whole, complexity usually shows up as dragging combat. A single skirmish against half a dozen wandering monsters in fifth edition can easily consume two hours of a three-hour session, dominated by movement measuring, saving throws, and decision paralysis. Before picking a replacement system, identify what you actually want to shed: the character sheet accounting, the combat length, or the preparation load. Different games solve different friction points.

Five games that feel like D&D with lighter rules

Each of these systems preserves the classic fantasy adventure loop of exploring ruins, fighting monsters, and finding treasure, but each strips away a different layer of mechanical overhead.

• Shadowdark RPG: the cleanest direct translation Kelsey Dionne's system is the closest modern bridge for fifth edition players. It keeps familiar six-ability scores, d20 roll-high checks against difficulty classes, and iconic classes like fighter, wizard, thief, and cleric. It cuts out bloated hit point pools, skill lists, feat trees, and complex action economies. Spells are rolled to cast rather than tracked across spell slots, dying characters have a tight timer, and torches burn down in sixty minutes of real time, returning genuine tension to exploration without adding rules.
• Dragonbane: tactical, reactive, roll-under fantasy Free League's Swedish fantasy RPG keeps the lighthearted heroic spirit and diverse fantasy ancestries of D&D (including duck-folk and wolfkin alongside humans and elves), but swaps the d20 roll-high system for intuitive roll-under skill checks. Combat is fast and tactical: characters get one main action each round, which they can spend attacking or hold in reserve to dodge or parry incoming blows. Willpower points replace spell slot bookkeeping, and characters advance by using their skills rather than calculating experience points.
• EZD6: rules-light action with zero homework DM Scotty's EZD6 is engineered for tables that want to sit down and play within ten minutes. Players roll six-sided dice, needing a six to succeed on standard tasks, modified by boons and banes that add or remove dice. Hit points are replaced by three to six strikes, armour saves prevent damage directly, and karma points give players a way to nudge bad rolls. Nine recognisable hero paths cover classic archetypes like skalds, warrioresses, and conjurers, making it ideal for groups fatigued by character optimisation.
• Knave: classless, inventory-driven d20 play Ben Milton's Knave uses standard d20 mechanics and the six classic ability scores, making it directly compatible with decades of classic fantasy modules. What it removes is the class system: your inventory defines your character. A character holding a spell book can cast magic; a character wearing plate armour is a front-line defender. Because carrying capacity equals your Constitution score, managing gear replaces managing skill lists, and character generation takes under five minutes.
• Cairn: problem-solving without combat bloat Yochai Gal's Cairn combines the minimalist framework of Into the Odd with classic fantasy flavour. Character generation is classless and takes three minutes. Attacks always hit, dealing straight damage reduced by armour to hit protection, meaning combat is brief, brutal, and treated as a dangerous hazard rather than a board game. When violence is lethal, players solve problems by questioning the environment, negotiating, and preparing clever ambushes rather than cycling through ability cards.

What you keep and what you leave behind

Switching to a simpler system does not require abandoning the fantasy stories your table loves. All five systems above comfortably run classic dungeon expeditions, wilderness journeys, dragon hunts, and royal court negotiations. Your players still play dwarves swinging battleaxes and wizards slinging fireballs. What you lose is the safety net of mathematical character builds where class features solve obstacles automatically.

In fifth edition, a character sheet is a bundle of pre-packaged permissions: spells like Goodberry remove survival logistics, darkvision removes light management, and high perception scores spot ambushes automatically. In lighter systems, players interact directly with the fiction. Instead of rolling an Investigation check to search a desk, the player specifies that they are tapping the bottom drawer for a false bottom. If your table enjoys tactical board-game optimisation, lighter systems may feel sparse; if your table enjoys clever problem-solving and rapid pacing, they feel liberating.

Transition checklist for a 5e group

Before introducing a simpler RPG to players accustomed to modern D&D, prepare these expectations:

• Run a one-shot adventure first rather than asking players to commit to an entire campaign in an unfamiliar system.
• Explain that low hit points and fewer defensive abilities mean combat is a high-risk encounter, not the default way to solve every problem.
• Remind players that their character sheet is an inventory and a quick reference, not a menu of allowable actions.
• Encourage players to describe what their characters do in the room rather than asking to roll specific skills.
• Keep character generation under fifteen minutes so that early character deaths feel like humorous twists rather than lost investments.
• Retain familiar habits where helpful: polyhedral dice, caller or mapper roles, and classic fantasy archetypes help players feel at home immediately.
