My girlfriend and I love playing games together, and one of my favorites is Minecraft. She likes playing it with me, but she gets bored after 15 minutes because there's nothing for her to do.
The problem is that she doesn't like building. She doesn't feel like she's any good at it, and finds it tedious and boring, so I don't really get her help with construction.
She DOES enjoy gathering, though, such as wood or food… But once we have two or three chests full of that, we obviously have no need for more, which ultimately leaves her without anything to do.
Sometimes, she'll spend an hour or so fighting mobs, but there's only so many times you can do that before it gets boring too.
And she often comments how bad she feels for not being able to contribute, so I want to find something she can do that will help me while also entertaining her.
