Do i need to reconnect all linked accounts and go through the entire process again? should this be tied to my account and handled via the cloud? Will galaxy 2.0 handle them completely separately? It appears that none of my accounts are linked in the settings and it is crashing 45% through import every time on my 2nd computer. I keep one in tv room and 1 in office and use both to game. Also i have a very large library.

That's a good question, I dunno if anyone on the forums asked them...

What I think it would happen is:
- yes, you have to reconnect all the links again (including downloading the files for the supported "non-official" platforms)
- after that, everything should fall into place, including tags, etc... because we know those info are on the cloud.

But in reality, I would not now how GOG would handle that!

I have used it on my laptop at the same time as in the desktop.
You WILL need to reconnect every integration.

But once you have reconnected the required accounts, everything in this list will be retrieved and synced between all of your PCs:

Custom metadata
Custom covers
Tags
Playtime for manually-added games
Manually added games (you will need to relink to the .exe though)
Rating
Friends

Bookmarks on the left side are NOT synced, but since tags and everything else is, you can just recreate them just fine.

You are able to edit things in one PC and they will appear relatively fast on the other one, and the library will look exactly the same (except for integrations not yet signed into)

Thanks to both replies, sorry i just now finally saw them. My 2nd pc still crashes on import so i am going to search for a post on how to read the logs and see what is crashing it - then post another thread if i cannot find it.
