RPG withdrawal is characterized either by 1 of 2 points:
1. All RPGs that one owns are completed and there are no more to be entertained with;
2. The futility of playing RPGs is suddenly dawning and one realizes there is no more point in playing/ creating them.
Often times, players of RPGs get drawn into them so far that they start shaping their real world to the form of an RPG, engaging on side quests, repeatedly calling the local pessimistic mechanic "Cid", noting the amount of money one owns(in cents) as GP or Gil, fashioning their own weapons and then carrying them everywhere they go.
This write-up, in no way shape or form, is written to bash the players of RPGs. However, if one possesses some of the symptoms listed, it is adviseable to take at least a week of non-RPG vacation.
