I remember GOG had a custom list feature, I quite liked it and found many of the lists people made very useful. What happened to the feature? Why don't we have it anymore?

You mean GOGmixes? Deprecated. :/

Those have been gone for years.

Which is unfortunately because EVERYONE needs CatMix.

If you like games with cats, you need CatMix to tell you what games to purchase.
If you don't like games with cats, you need CatMix to tell you what games to not purchase.
Everyone wins with CatMix.

By that, I mean all the random games that happen to have cats in them but are not tagged cats as they are not the main feature... but they are.

They were removed when the 2018 redesign hit. There was some PR blah blah as to why.

Depre-cat-ed.

There is free tube premium for all the Gogers, just paste your song into your profile, and boom! No adds : )
Gogmix back or else... ^

I rarely play music on my PC, just on my Hifi System in the car, bedroom, lounge or phone + headphones.
SO GOGmixes were lost on me, and I've never missed them. LOL

But hey, a lot folk here seemed to like them, so maybe they should come back. ;)

GOG should at least try to cater for everyone.

Come on, who needs gogmixes when we got glorious TAGS

I liked having a GOGmix for games with awesome music.

There would be quite a few on that list I imagine.

I'd certainly put Vampire: Bloodlines, Bastion and the Hotline Miami games on that list.
