No revenue estimate for XBOX — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $40.6M — a different platform, not this one.
Tainted Grail: The Fall of Avalon is a mature, first-person perspective open-world RPG, taking you into a dark fantasy world inspired by Arthurian legends.
Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 1.14/day in the week to Sep 1 → 1.71/day in the week after.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Xbox · Most Wishlisted · United States has just 14 day-to-day chart moves that followed a price cut, against 2,422 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
Stats
How fast this game is gaining ratings — the activity signal available where a store publishes no sales or install numbers.
Measured from our own daily snapshots, not reported by the store. Deliberately not converted into sales: a one-tap rating's ratio to copies sold is unknown on this platform, and guessing it would be worse than leaving it out.
Sums Steam only; Xbox, GOG publish no volume signal, so the true total is higher by an unknown amount.

13 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
13 on sale2 answered “not sold”0 we did not ask
The 2 “not sold” markets are read from the Xbox price pass of Aug 27: that day the store answered for this game elsewhere and gave no price in those. The 13 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 0 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.
