Power Creep

A permanently purchased item in the game becomes less valuable over time.

Power creep is a term used to describe a situation where an item in a game depreciates in value over time. The main way this happens is via new content being added to the game that make the old content less valuable.

The idea is that you may have earned or paid for a powerful item or upgrade in the game. It may have been great for awhile, but new better items are available or the power level of the opponents has increased to the point where that original item is no longer useful. The money and time that you previously spent to earn that item is now worthless and you must spend more money and time on the new more powerful item to have the same benefit that you had before.

If games do this often, it encourages players to keep spending money to stay competitive. If done incorrectly by the game developer, it also has the effect of making the game boring for new players who start with the new powerful items which are overpowered against the opponents found in the beginning of the game. The original game can become unbalanced if too many updates are made that keep adding more and more powerful items.
