Playing a variety of games I noticed that some concepts are "trapped" in the realm of roguelikes. One of the most intriguing game-play elements in roguelikes is the unidentified item. The unidentified item can be used at any time adding another layer of randomness and chance to the game-play. I think the reason this element cannot co-exist with a saving mechanic is that you could save, use the item and then load if you are unhappy with the results. I am still puzzled if this mechanic is overlooked and it could possibly be successfully incorporated into some modern games? If you do know of examples where it is being used, please share.
