I think the number of times bundled is important. Then again, this number is different between Barter and ITAD since rebundles are considered differently.

I guess the main problem is that neither Barter or ITAD have a complete database of bundles. We managed to add a lot of the missing bundles from the past 2 years on Barter, and with the huge contribution of theemu and others, Barter was extended to other platforms too (for example GOG); however, it lacks old bundles, the ones released before 2015.

On the other hand, ITAD lacks a lot of information, not only in regards to the permanent stores mentioned above but also a lot of the Go Go / Otaku, HRK, G2A bundles etc... And not only that, but the information is a bit messed up when it comes to games having the same name, since unfortunately ITAD doesn't work based on the app ids as a primary key, but based the game name.

The script could rather easily be extended with a column linking to Barter, but we need to ask the admin first if this wouldn't overload their servers. Pulling the data from Barter would be a more difficult thing to implement though.

I will make a note under the chart that "In Fear I Trust" has been included in the HRK Make A Bundle.
