OCD things you do in games.

[Ouberry_13]

Always save twice whenever a save point/enemy-clear area is present.
Reloading after every kill
Always checking to make sure an enemy isn't behind that one door off in the distance
Always playing as a mage character in MMO's
I must have a multiple of 10 of any health potion/tonic/food/etc. or else I feel off
Talking to every NPC I see, just to be sure I don't miss anything
I must pick up anything an enemy drops, even if I know I will only sell it once I find a merchant
My health must be full whenever I'm not in battle
If one of my party members in an RPG has a status ailment, it must be recovered in the next turn
In an RPG, my entire party must be equally leveled, because I always have a nagging feeling the game is gonna force me to play as one of the characters I don't like.
If playing a co-op game, my entire team must be alive at the end
If playing a fighting game, I never use supers or ultras on the first round, only normal and special attacks
