It seems impossible to comprehend now, but in 1969 three government employees climbed into a rocket and blasted themselves to the moon—even though there were no fish there. They bounced around, they drove a buggy, they picked up rocks, but the journey was ultimately pointless because there were no space ponds and no moon fish to catch. Why do you think we stopped going?
Fast forward to today, and it's exceedingly rare that I'm even gonna bother to play a videogame if there isn't a fishing minigame in it.
