A certain flaw in game balance design, where content released later tends to get more powerful as time goes. This can be seen in multiplayer games that have regular expansions or balance patches.

Power Creep can also refer to the average increase in relative power for all released content in a game.
The changes described by Power Creep happen slowly and might not be noticed by the players for a while, until comparisons are maid, hence the "creeping".

Similar Term is "Mobility Creep" - here newly released characters in Multiplayer games tend to receive more mobility spells, that allow them to traverse the map quickly and more effectively in comparison to older characters.

Those balance flaws can be mostly observed, because game developers want to create more fun and engaging content, but often power and speed are fun to play with.
The latest expansion really showcases the power creep in this game.

Remember this Character, he used to be much weaker back then. Talk about power creep.
