That said it does seem like a great addition to other studies in a language, which is how I am able to use it, my biggest frustration speaking Swedish is that my vocabulary is really limited and I basically run out of words. I reach for a concept that I know in English but can't really translate it over and sometimes those gaps can be surprisingly basic.
For example last night I wanted to say after learning that my daytime classes would start at 8:30, I sent a message to my partner about it basically complaining that "I need to way up so early", in order to get practice I try to send messages like these in Swedish but quickly realised I don't actually know how to say "so early", so the message was only half in Swedish "Jag behöver vakna so early".
So for me anything that helps me add more words to my vocabulary is pretty helpful, especially something that helps add geography to the list Influent it gives me a way of using spacial memory to help learn.
The flight sim minigame is still pretty strange though.
