Let's say I add and tag a hundred PS2 games to my GOG Galaxy 2.0 list.

If I ever reinstall GOG Galaxy 2.0 on a different computer, will the added games still be there, or will I have to manually add them all again?

If they aren't saved to my account, is there any way to export the list of added games so they can be imported again later?

Thank you so much for the clear reply!
I'm glad. Galaxy 2.0 seems like it'll be a perfect personal game catalogue.

now that we can add our own non-Gog games in yes Galaxy 2 is much better... perfect is a strong word

just need to save bookmarks in the cloud in a future update ;)

You're welcome! And indeed, this ability to sync most of the library has made Galaxy by go-to launcher, there is absolutely no contender. Once the unified friends list is available and they add a DLC manager if possible (mainly just because the Xbox games' DLC is a mess to manage and you can only do so from the Windows 10 Store, and not every DLC is listed in the game's page and you gotta go to the Downlaod menu in the Store. I'd rather be able to manage DLCs from Galaxy).

By the way, forgot to mention, playtime is indeed synced too! Including playtime for manually-added games.

Hello,
Is playtime from manually added game is saved in the cloud too ? Ty.

Aye, confirmed it myself by logging into a laptop and installing Galaxy 2.0 there. Not only does it show manually-added games, but also their playtime!

Nice !! Thank for your answer ;)

This is a truly rad feature. I had no idea I would be able to add every game I own under the sun to this platform AND have the whole thing cloud-synced. You are amazing.

Now if I could just check my collection remotely...
