Tainted Grail: The Fall of Avalon

Tainted Grail: The Fall of Avalon is a first-person open-world action RPG from developer Questline, published by Awaken Realms. It draws on the Arthurian tradition but takes a grim, dark turn. The story unfolds about six hundred years after King Arthur's death, when the realm lies in ruins and the world seems trapped in an eternal autumn. The choices you make along its branching main storyline are meant to shape what becomes of Arthur's legacy.

Most of your time goes to exploring three large regions, taking on main quests and a long list of side quests, and talking with a big cast of characters. The store page cites more than 250 non-player characters and over 200 side quests, with a full adventure that runs 50 to 70 hours. Between fights, you can keep a sketchbook, fish, farm, forge, brew alchemy, cook, mine, and manage a house, so the world never feels like it exists only for combat.

Combat asks for the most attention. Weapons range from melee blades and shields to bows, magic, throwables, and mixed item types, and you can switch between them smoothly. Precise dodging, parrying, and blocking matter because enemies hit hard and a single mistake can be fatal. The store frames the game around building your own fighting style, whether that means a brawling alchemist, a summoning blacksmith mage, or a stealthy archer hiding in the shadows.

Nightfall brings a chaotic primal force that warps reality and makes the world far more dangerous, so you cannot simply coast through the day. Moral lines blur as your decisions test your conscience. Hidden items, secret dungeons, unique enemies, and story hints are scattered across the map for players who like to wander off the marked path.

Steam reviewers rate Tainted Grail: The Fall of Avalon Very Positive, with 88% of reviews being positive. The review volume is in the tens of thousands, which gives the rating real weight. A score this high across that many reviews suggests a consistent experience rather than a lucky streak of enthusiastic early buyers.

Steam's labels are based on the share of positive reviews, so an 88% rating still means roughly one in eight reviewers were not satisfied. Before you buy, skim recent reviews to see whether the complaints match your priorities, such as combat difficulty, pacing, or technical issues. A large review count is generally more reliable than a small one, and this game's volume is well past the range where a few loud voices dominate the score.

All prices here are Taiwan Steam store prices in NT$. The game currently costs NT$ 469, down 30% from its regular price of NT$ 670. It is not free to keep at the moment, and we have not recorded a free-to-keep offer for it.

The lowest paid price we recorded was NT$ 335, a 50% discount from the regular NT$ 670, on 2026-07-21. The game is discounted often, and its highest recorded price matches the regular NT$ 670, so the discounts have been a regular part of its pricing.

Our price record is still short, so this verdict is tentative. The current NT$ 469 is not our recorded low, which suggests waiting could pay off if you can hold off. If you want to play now, though, NT$ 469 is a reasonable price for a large, highly rated RPG, and the game's track record of deeper discounts is worth keeping in mind.
