Water is on the planet...therefore, moons do affect planets.
Wait! There is more! If we lose our moon by it not existing or falling out of orbit, the Earth's rotation would be affected and speed up. It is the dynamic of distance, pull, momentum that causes us to rotate at the speed we do. We would end up with only the Sun's pull which would cause our day to be 1/2 to 2/3 shorter. The faster rotation would mean great changes for everyone...think of the surface winds, the 8-12 hour days, so many other things affected by this. In the game it translates to what was mentioned...the sea, the crops, the monsters, etc.l
Your use of barycentre is wrong. A barycentre is the center of mass, not the center of a planet. A center of mass is established like the moon(s) rotation and the planet in balance with each other. Our Earth does not sit and spin. It rotates and orbits along a fixed line that is in balance with the bodies around it, that are also doing the same thing. That spot, that center which the earth and its bodies orbit in balance is your barycentre...your center of gravity/center of mass.
