You could always sit down and watch a movie with your family. However, video games are more involved involve and encourage talking and working together as a family. Minecraft is a great game for families to play together. It tends to fall on the easier spectrum of games to play as long as you have a crafting guide on hand. Having the wiki page open also helps.
There are so many things that you and your family could do together from exploring the wild landscape, to building a house, to taming animals. If you get tired of the same old things, you could always open up a server to your relatives and the cousins could join in as well. All you need is a good online gaming server to get started. It is a great way to spend quality time with everyone. Imagine everyone building their own little Minecraft houses together while chatting and laughing over a video call.
This sounds all good and fun. However, what do you do if you want more of a challenge. If you want more of a challenge, it may be time to upgrade to a modded server. A modded server allows you to add more things to the game such as dangerous enemies seen in this video. Mods can also add more blocks to build with and machines to engineer.
