A fairy-tale DLC chapter for Dungeons 3 that wraps familiar dungeon-building mechanics in a storybook skin. Worth it if the base game already has its hooks in you.

Once Upon A Time is a story-chapter DLC for Dungeons 3, the dungeon-management and real-time-strategy hybrid from Realmforge Studios. If you have not touched the base game yet, this is not your entry point. But if you have already spent a solid stretch micromanaging imps, slapping your minions into productivity, and terrorizing the overworld surface armies, this DLC gives you a new self-contained campaign to burn through without demanding that you relearn the system from scratch. The fairy-tale framing is the headline selling point here. Realmforge leans into the storybook aesthetic with narration that pokes fun at fantasy tropes, enemy designs that riff on classic children's story archetypes, and level objectives that feel deliberately theatrical. For a DLC, the tonal commitment is genuine rather than cosmetic. The humor is hit-or-miss depending on how much mileage you have already gotten out of the base game's sardonic narrator, but the mission structure stays interesting enough to carry players who find the jokes wearing thin. From a mechanics standpoint, Once Upon A Time does not introduce sweeping new systems. What it does deliver is a curated set of missions that force you to prioritize differently than the base game's campaign. Resource pressure and unit management remain the core loops: you are still digging out rooms, assigning minion types to the right chambers, and timing your surface raids to hit before defenses consolidate. If you are the kind of player who liked optimizing room layouts and staggering wave timing in the base campaign, those same levers are here and the mission design gives them context. If you found the base game's mid-campaign pacing sluggish, be aware that DLC chapters inherit those same structural rhythms. The AI on the overworld side holds up about as well as it does in the base game, which is to say it is competent enough to punish sloppy play but not sophisticated enough to surprise experienced players. Veteran Dungeons 3 hands will find the difficulty curve on the lighter side unless they self-impose constraints. The DLC is clearly aimed at completing the narrative arc rather than testing mechanical limits, which is a fair design priority for this format but worth knowing if you are after a serious late-game challenge. Mod support is not a factor here since Once Upon A Time is a contained story chapter rather than a toolkit expansion. The value proposition comes down to one question: how much do you like the base game's core loop? If the answer is a lot, this is a comfortable few hours of additional content with genuine production effort behind the presentation. If you bounced off Dungeons 3 proper, nothing here will convert you. Diego, Scout Team

GamerScout Verdict

Solid extra content for Dungeons 3 fans who want more of the same with a storybook twist, but skippable for anyone still on the fence about the base game.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
