Having dolphins and orcas doesn't automatically mean there will be dolphin/orca show. We can have animals but exclude show feature from the game system I think.So you would be happy if this game had dolphins and dolphin shows?
Actually, just having dolphins and orcas and no show feature can open another fascinating scenario. We get some small cetacean mammals 'rescued from marine-show-thingy'(just a plot setting BTW) and our job could be rehabilitate them and let them live happy without any need to perform on shows, or eventually free them to the wild.
