A few, for example, might be:
- Feeding your characters
- Day/night cycles
- Resting for character/party recovery
- Crafting
Numerous games have foregone such things, and have still been wildly successful - games like the Final Fantasy series, for instance. Many others, however, feature systems for time cycles, resource gathering, crafting, and other tasks that could be considered irrelevant to play or the general game objective - yet have found tremendous interest in game communities.
My question to you is:
Do you feel that adding mundane articles to games brings added realism and depth to a game, or do you feel that it's pointless or could possibly even detract from the enjoyment of a game, or simply should not be included unless it somehow adds to the story or is specifically required to complete a game?
