I got these “presents” on my 43rd birthday from my kids. Completely unexpected. My older son created “Doctor Who World” that for some reason features Iron Man – which I think is an intriguing idea.
And his younger brother took the idea and made his own “Mystery World” and tried to write some German birthday greetings all by his own (he’s 5 and has only been to Germany once early this year). This is one of the moments where being a father is actually really cool.
