Hey there! Amazing content. I'm just starting with Vue and being able to read this helped the process of understand more about Vue.

One question tho. I noticed that there was a Vue warn saying 'Error in callback for watcher "favoriteGame: TypeError: Cannot read property 'toLowerCase' of null', what does this mean?

It means that the variable that you are using toLowerCase on does not exist. Can't really tell without seeing the code though.
Glad you liked it!
