The game bundle SEGA Mega Drive & Genesis Classics (https://www.igdb.com/games/sega-mega-drive-and-genesis-classics) contains a large amount of games on the webpage, but in the API only one game is returned, sonic:

'fieldsname, url, bundles; where bundles = (80185); limit 50;' https://api-v3.igdb.com/games
[
{
id: 3192,
bundles: [
4157,
7189,
20502,
20621,
22297,

86067,
96393,
99953
],
name: Sonic the Hedgehog,
url: https://www.igdb.com/games/sonic-the-hedgehog
}
]

If you pick one of the games listed on the web page as in that bundle that is missing from the API, for example Gain Ground, the web page for Gain Ground says it is available in the following bundles:

Sonic's Ultimate Genesis Collection, Sega Genesis Collection, SEGA Mega Drive & Genesis Classics, SEGA AGES Sonic The Hedgehog

But the API responds that the game appears in the following bundles:

'fields name, url, bundles.name, bundles.url; where name = "Gain Ground";' https://api-v3.igdb.com/games
[
{
id: 3129,

I submitted a game prologue, which was rejected because it was a demo.

However, I marked that game as "played" before it was rejected. Now, I have a ghost "played" game, whose existence is given away by the game count.

I would like to be able to remove that "ghost" game from the list, but it is not visible in the list, and I don't know its IGDB ID, so I cannot forge an API request to remove it from the list.

A simpler fix would be NOT to count "ghost" games when counting the number of games in a list. This way, the existence of the "ghost" game would be completely hidden.

As some reviews age, some sites can go out of business or just shut down. However there doesn't appear to be an automatic way the database removes or reports broken links or updates scores as they go away. Additionally, some of these will push scores averages down if they continue to inaccurately are placed as Review Scores, yet hold broken links.

My Search query to IGDB API is failing with status code 400 if the search text contains a back slash \ in it:
I am using below syntax:
const { q } = req.query
let fields = name, collection
apicalypse(requestOptions)
.fields(fields)
.limit(50)
.search(q)
.request('/games')
.then(response => returnResponse(response, req, res))
.catch(err => returnError(err, req, res))

requestOptions are like this:
const apiPath = 'https://api-v3.igdb.com'
const defaultHeaders = {
'Accept': "application/json",
"user-key": apiKey
}
// Apicalypse Request Options
const requestOptions = {
queryMethod: 'body',
method: 'post', // The default is get
baseURL: apiPath,
headers: defaultHeaders,
responseType: 'json',
timeout: 10000
}
q is \ if I send \ from front-end & abc \ xyz in case of abc \ xyz.

The current popularity value for a game doesn't make any sense.
Please see below examples showing the popularity value with the hypes, and number of user ratings.

"id": 115278,
"hypes": 1,
"name": "Rune Factory 4 Special",
"popularity": 2090.622837928576

"id": 120268,
"name": "Zombie Driver: Immortal Edition",
"popularity": 1431.973719413489

As you can see, the top 2 games by popularity both have 0 user ratings. How can these be the most popular games on IGDB?

The docs say 'The popularity number is calculated using usage statistics of game pages at https://www.igdb.com' which can't possibly be true if these games are at the top.
