For the life of me I couldn't think what Joe Montana's nickname would have been that contained 'Sky.' Finally figured out it was the state of Montana with a few seconds left. Jeez...
What, no Sky King? (Jk, it was a TV show when I was a kid during the Middle Ages, but oddly enough it was the first thing I thought of when I saw this quiz.) "From out of the clear blue of the western sky comes Sky King!"
No Man's Sky would be a good addition to this quiz. A game famous for disappointing everyone at release and then slowly improved to become an incredibly popular game.
Removed from the quiz.
How about the sky is the limit?
