If you enjoy spending long hours doing menial boring, non-interactive repetitive meaningless tasks which require the amount of skill it takes to click all of two(2) buttons on a mouse, OSRS is the game for you.
If you enjoy watching drooling an over animation a pixel on a screen for many tens(10) of hours while you click repeatedly at almost zero(0) difficulty to yourself, except perhaps the difficulty challenge of sitting farting for such extended long lengths of time, then OSRS is the game for you.
However, if you also enjoy role-playing flaming, merching scamming, gathering loot visage, discovering new content in a nostalgic realm updates, and gaining levels wasting time in general, OSRS is for you.
