LOL is different from Lol,
LOL is League Of Legends and Lol is Laugh out loud.
ROS is different from Ros,
ROS is Rules Of Survival and Ros is my Rules of Saving (You).

ML is different from Ml,
ML is Mobile Legend and Ml is My love for you.
But Online Games are not so different from Me,
Online Games are the things you play and Me is a piece you also played.
