Reward is a Specification of the Non-Spatial Property.

Reward means the resource is gained as a reward for performing some kind of action, unrelated to actually collecting resources.

Reward is fairly non-descriptive, as rewards are very game-specific, so it is hard to come closer to the actual action being performed, but they refer to level progression, quests, or winning a match (league of legends).
