Where The Legend of Bum-Bo sits on the grid
Compare the whole catalogueThe Legend of Bum-Bo plotted on the axes the GamingPickz Score is built from, on the full 0 to 100 scale so its position is its real one. Change either axis to see where it lands.
1 games have both
Players. The share of Steam reviews marked positive, pulled toward the catalogue average in proportion to how few reviews stand behind it. A game with 200 reviews moves a long way toward the average; one with 200,000 barely moves at all. Without this a title sitting at 100 percent on nine reviews outranks Half-Life 2 at 98 percent on 278,000.
Popularity. A blend of two things that are not the same. Audience is how many people wrote a Steam review, which is a floor on how many played it. Reach is how many language editions of Wikipedia document the game, which is cultural footprint rather than sales. A game can score high on one and low on the other: a huge free-to-play title has audience without reach, and a landmark console exclusive has reach without a Steam audience at all. Where both exist they are averaged; where only one does, that one carries it.

Every point links to that game's entry. The value map and the reception map are fixed views of the same data.
How positions are decided
No paid placement, no favouritism, live third-party data
- Placed by the published method, not by us. Every coordinate is computed from the axis definitions and weights printed on this site. Nobody moves a point. See the axes.
- Nothing here is paid for. No sponsored placements, no promoted slots, no arrangement of any kind affects a position. If that ever changes it will be labelled and sit outside the ranking.
- No favouritism, including our own. The 16 games we have written full reviews of are scored by exactly the same formula as the other 1,510, from the same third-party inputs, and they land where it puts them. Our own opinion of a game does not enter its coordinates.
- A position is not an endorsement. It says how a game was received and what it costs, not that we recommend it. Where we do recommend something, it carries a written review with a name on it.
- Fetched from live third-party data. Player sentiment from Steam, critic aggregates as published on store pages, prices checked hourly, attention from Wikipedia. Each figure carries its source and the date it was read, and we do not adjust any of them.
Is The Legend of Bum-Bo still active? Players right now
The Legend of Bum-Bo has a small, niche following: 10 people were playing at once when we last read Steam on 19 October 2026. This is a snapshot, not a live counter, and it is a recent concurrent reading rather than an all-time record. For what is trending across the catalogue right now, see the pulse.
How many people own The Legend of Bum-Bo
This is an estimate, not a sales figure, and the two are not interchangeable. SteamSpy samples public profiles and publishes a range; the range here spans a factor of 2.0, and that width is the honest part of it. We show both ends rather than a midpoint, because a midpoint would look like a measurement.
Steam only. Console and storefront sales are not counted, so a game that sold heavily elsewhere reads low here. Read on 19 October 2026. Where a publisher has announced a real unit figure, that appears separately and carries its source.
Estimated sales for The Legend of Bum-Bo
These are estimates, not reported figures. Edmund McMillen has not published unit sales for The Legend of Bum-Bo, and nobody outside the company can measure them. What follows is arithmetic on the review count, with the method printed below so you can check it or reject it.
How this was calculated
Steam sales track review counts closely enough that dividing one by the other across games with published figures gives a usable multiplier. This is the standard method for estimating sales from outside a publisher.
| Reviews on Steam | 5,934 |
|---|---|
| Sales per review | 30 to 60 |
| List price | $14.99 |
| Assumed average selling price | 33% to 66% of list |
| SteamSpy owner estimate | 1.0M–2.0M, a different measure, see below |
What this cannot tell you
Steam only. Console, Epic, GOG and retail sales are not in here. For a game that sold heavily on PlayStation this is a fraction of the real number.
The band is wide because the method is imprecise. Review rates vary with price, genre, launch era and how insistently a game asks. Published analyses put the ratio between 30 and 60 for paid games, and we show the whole range rather than picking a point in it.
The owner estimate above measures something else. SteamSpy counts accounts that have the game, which includes free weekends, bundles, giveaways and gifts. It sits higher than a sales figure for that reason, and the two are not alternative answers to the same question.
Revenue is the shakiest line. It assumes an average selling price well below list because most copies move in sales, and it ignores regional pricing, refunds, key resellers and whatever deal the publisher actually has with Valve. Treat it as an order of magnitude, not a figure.
If Edmund McMillen publishes a real number we will use that instead and say where it came from. Our editorial policy covers how we handle figures we cannot verify.
The Legend of Bum-Bo price & deals: is it on sale?
We have one reading so far: $14.99 on 30 August 2026. Prices are checked daily from here, and this becomes a chart once there is more than one point to join. A single observation is a price, not a history.
What readers say about The Legend of Bum-Bo
Reviews written by people who have played it. These are separate from the GamingPickz Score and are never averaged into it: that score comes from thousands of Steam reviews with a sample-size correction, and a handful of unverified ratings would distort it rather than improve it.
