Has anyone seen any Whales? Whale-Fish? Giant Squid? Megalodons? 
Come on MSFS/Asobo… That is a mighty big blue ocean out there. We had the Megalodon in Battlefield. Give us one here, every day, in a random spot. Let’s see how long it takes us to get a screen print to prove it!
In other games this always caused a sensation. It could help the sims popularity for sure. Heck… If you are flying at twenty feet or below that bad-boy would swallow you clean! GA only, of course.
