* In {{Roguelikes}} (''VideoGame/{{Angband}}'', for example), items are usually unidentified when you first find them, and they can always be generated again later. This includes unique "artifact" items, but only if you ''don't identify them'', since artifacts are only generated once ''per game''. If you ID an item and it turns out to be an artifact, it is permanently missable when you leave the level and you're not carrying it.

* In ''VideoGame/MedievalIITotalWar'', generals can sometimes gain Ancillaries, technically characters following them around but essentially a stat boost. Most of them are gained through specific but generic actions like winning battles or being in a town/castle when a given building is completed. However, some of the most powerful ancillaries are historical ones like William Wallace or [[Creator/NiccoloMachiavelli Machiavelli]], and those can only be gained in very specific circumstances that aren't revealed to the player [[note]]unless he has peered through the game files[[/note]]. UsefulNotes/JoanOfArc, for example, can only be gained during a 20ish year span (1 turn being 6 months in the game), only for French players, only if France and England are at war late in the game (which is unlikely, since both countries are in each other's way, and one usually destroys the other in the early game) and only if the given general wins a battle against the English ''in which the odds were against him, but not too much''.

* ''VideoGame/WarThunder'': Several low tier gift vehicles and minor cosmetic items have been released during timed events only in an untradeable form, which means that you won't be able to purchase them on the marketplace later and so if you miss the event itself you will never get those rewards. Also, this is partially en force with tradeable vehicles too, since they are in limited supply on the marketplace depending on how many players unlocked them, and some have been all sold during years - plus sometimes their price is so high that realistically you will never buy them regardless.

* In ''[[VideoGame/QuiltsAndCatsOfCalico Quilts & Cats of Calico]]'', there are {{Sidequest}}s you can do in Story Mode to gain rewards, but if you don't do them before finishing the plot-important puzzles in an act, you won't be able to access them again.

* Missed out on the Dr. Pepper promotion for ''VideoGame/NeedforSpeedHotPursuit2010''? Say goodbye to any chance of getting the Dodge Viper SRT-10, Nissan 370Z Coupé, Porsche Cayman S and the Porsche Panamera Turbo for the Racer faction. Thankfully those cars are included in the Remastered version along with all the other DLC cars.
