=== Examples ===

== Using the pattern ==
[[Ephemeral Goals]] are often also [[Preventing Goals]], simply because a player that is  striving towards an such as goal presents himself or herself as a target only from when first observed until the goal is reached or impossible to any longer reach. In these cases it may be difficult to provide specific [[Rewards]] related to the ephemeral aspect of the goal (prevent the other goal may be its own [[Rewards|Reward]]). Games that want to acknowledge the possible [[Game Mastery]] required to succeed with these types of goals may use specific [[Achievements]] - the ''Level a Charge'' and ''Fuel Crisis'' [[Achievements]] in [[Left 4 Dead 2]] are both examples of this<ref name="L4D2"/>.
