No energy regeneration
Energy depletes with use but does not automatically return over time, forcing the player to seek external sources to replenish it, sleep, or use some other method of restoration.
Alternate names: No mana regeneration, No magic point regeneration, Finite energy, Finite magic, Finite mana
The first video game about No energy regeneration was released in 1989.
Usually means player must rest, recharge batteries, drink potions, eat mushrooms, meditate or something else to recharge this energy.
This tag is especially important when all energy restoring methods have only finite use, either because they simply run out or they have other limitations.
