Have my bump, since search isn't even working for some stupid reason.
'No results found" for literally anything I search for, tried on 3 browsers.

Did you clear cache and that sort of things?

The new search feature? It works kind of fine here. however, it seems it needs a better wildcard handling.
(URLs trimmed as I cannot post thanks to the negative rep...)

Search cyber. 8 results (CP2077 included)
gog.com/games?limit=48&query=cyber&order=desc:reviewsRating&page=1

Search unmetal (and released 2021).Returns The 2 UnMetal:
gog.com/games?limit=48&query=unmetal&order=desc:reviewsRating&releaseDateRange=2021,2021&page= 1

But searching metal (and released 2021) does not find anything...
"We couldn’t find anything matching your criteria.Try to refine your query and filters."
gog.com/games?limit=48&query=metal&order=desc:reviewsRating&releaseDateRange=2021,2021&page=1

If I click the "magnifying glass" icon (upper right corner) and type metal, the drop down results list contains unmetal too. So lets welcome a new -inconsistency at the GOG style- (TM pending) I guess...

And on topic: The bestselling all-time filter is not available here yet.

Up!

Please, bump threads in a more natural, organic way. ;)

Cyberpunk 2077 is 2nd best selling game of all time? (might be if they based it off price per unit instead of units overall imho??)

Stardew Valley is on the first page too. Wow.

They should have a separate Indie best selling all time list :D
