Shooting, chasing, exploring - hit video games tend to have themes that set the pulse racing.

That smashed a record for concurrent players set by the somewhat more adrenalin-filled Fortnite.
What is it about this plant-growing simulation that has got so many people hooked - and could it persuade more people into real-life gardens?
