I hear the term casual being thrown around a lot in Orbus, I just wanted to give my two cents about casuals vs hardcore.
To me, time does not determine whether you are a casual or a hardcore player. I don’t care if someone plays for an hour at a time, or if they play for hours at a time.
What determines a casual from a hardcore player is their mindset. “Are they willing to go through the same activities - losing time and time again - to learn mechanics and wouldn’t stop untill they succeed”. If yes, most likely you are a hardcore player. If no, the opposite.
