Although the feature of save games often allows for gameplay to resume after a game over, a notable exception is in games where save games are deleted when it is game over. Several names are used to describe this feature, including "permadeath", "iron man", and "hardcore", and the feature has developed over the years from being the only kind of save system per game to the more modern 'suspend game' feature among regular save points. For online games, the game's progress is maintained on the remote server. In some games, upon resuming the game from a save game, the software locks or marks the save game. Early examples include "Moria" and "Diablo II" "hardcore" mode where the character save game is managed by the server. The use of saved games is very common in modern video games, particularly in role-playing video games, which are usually much too long to finish in a single session.
