My kid finished Alba: A Wildlife Adventure yesterday. It's a single-player game, but she can't read yet and there's quite a lot of talking in the game, so I had to sit next to her the entire time anyway.
It's a cute game about a little girl who is staying over at her grandparents on an island, with most of the gameplay revolving around taking pictures of all of the wildlife on the island. In between you also help clean up a bunch of litter, help some injured animals and prevent a hotel from being built on a nature reserve.
