From what I can ascertain from Aunty Google, yes you can delete a game from your account but you must do it via steam support.

If you're looking at the game page in your library, you should see a Support link at the right end of the ribbon under the Play/Install button. That will take you to the Support page for that game where one of the options says "I want to permanently remove this game from my account".

Do keep in mind that this is simply an advanced hide feature. The license is still tied to your account but it is just deactivated. You can reactivate it at a later time for this account without having to buy again.

Also keep in mind that your playtime and stats for those games will still be on your profile even though you've asked Steam to remove it from the account.

Basically if you want to buy the games again, and associate them to a new ubisoft account that hopefully you'll manage a bit better, you're going to need a new Steam Account.

A lot of people end up in your boat, and have the same thoughts. But those thoughts are based on some assumptions about how Steam manages licenses.

1. Removed from your library doesn't mean removed from your account.
2. You can't have more than one license for the same game on a single account.
3. You cannot remove the license from your account.

#3 you could argue about all day because there's reasonable use cases for completely removing a license from an account, and making removed games recoverable. And arguably the trade off of being able to recover removed games has more benefit than allowing people to truly delete the license. At least from Valve's perspective based on their implementation.

pls help

If you have follow questions, ask them here.

Firstly you try to recover your Ubisoft account. If you cannot recover your Ubisoft account you need to do the following:

Create a new Steam account, create a new Ubisoft account, install Ubisoft Connect and sign in, link your new accounts, purchase the games.

Why?

You cannot link your current Steam account to a new Ubisoft account as it remains tied to your old Ubisoft account.

That won't remove the licenses nor the Ubisoft account linking.

You know the email, just don't have access to it, or you don't know email at all?

This is why use password manager help you keep track, and it best to use few to several emails example one for personal like work, banking, and etc, one for gaming, and stuff, and one for throw away for things you don't care if anything happen to it. There really isn't any reason make mass amount of emails unless doing it for special reason, the more you make, the more you have to manage kind of deal.

Ubisoft can help you recover your account if you know your email tied to your account, they will ask for proof on number of things.
