Cozy Games

I see what you're meaning, when the game is more or less resetting you to just before you started the fight or what have you, if there's no items lost or permanent repercussions to the death, then keep going around that loop.

However by this description, Call of Duty would be cozy. I think this post is more or less about games / game functions that don't cause frustration or raised blood pressure.

In both titles you mention, it might not be 'cozy' for someone to spend fifteen minutes on either a boss fight or trying to reach level 100 in Skull Cavern, only to lose all that time and effort because your hitpoints or time remaining fall to zero.
