What builds suspense in pretty much every element in life is when you care about something but are missing crucial information relating to it. And hey - it turns out every challenging game has unknown outcomes everywhere! You don't know if you’re fast enough to hit the ball. You don't know if your enemy has a trap card. You don't know if you’re going to roll something amazing or awful. You don’t know if your teammate is going to pull through or fail.

The problem is that you usually need to make decisions without being 100% sure what the outcome will be.
