I want to come up with some games that my family can play together on our phones or computers or something (we all love Nintendo, computer games, etc) and I just want some things we could collab on.  Please help me brainstorm some ideas and how they would work for my family. 
There are plenty of options that your family might enjoy. Here are a few of them:
- Minecraft: There are many ways your family can play together on this platform, including minigames, building competitions, and quests. 
- Fortnite: Battle with and/or against your family members with this game. 
- Family Fun Pack: Conquest Edition: This isn't a game so much as it is a collection of classic games like Scrabble and Battleship that your family will be able to play on your devices so you can save your table for food and other things. 
- Mario Kart: Almost all the Mario Kart games can be played against other members of your family. Have fun racing each other to the finish line.
