1. A system for hosting an online game, and for enhancing server availability, the system comprising: a game server including one or more physical processors configured by machine-readable instructions to: execute an instance of a game to generate information for transmission over a network to a first client computing platform to facilitate presentation of the game to a first user on the first client computing platform, and to implement in-game actions in the instance of the game in response to action requests for the in-game actions by the first user, wherein the in-game actions include actions of a first action type and actions of a second action type, wherein actions of the second action type are enhanced versions of actions of the first action type, and wherein actions of the first action type and actions of the second action type have individual costs in resources that are available in the game, and wherein the game includes a plurality of resource types, the plurality of resource types including a first resource type; initiate transmission over the network of the information generated by the execution of the instance of the game to the first client computing platform, and to receive over the network from the first client computing platform action requests input by the first user on the first client computing platform, wherein action requests specify execution of in-game actions; maintain user resource records, the user resource records including a first resource record for the first user that indicates amounts of resources of the individual ones of the plurality of resource types that the first user controls in the game including an amount of resources of the first resource type; and determine whether the action requests received over the network from the first client computing platform during one or more time periods is for an action; and effectuate, in response to a determination that no action requests for an action of the first action type was received from the first client computing platform during the one or more time periods, an increase of the amount of resources of the first resource type controlled by the first user, wherein transmission over the network is initiated to the first client computing platform of information that causes the first client computing platform to present the increase of the amount of resources of the first resource type controlled by the first user, wherein execution of an action of the second action type has a cost of resources of the first resource type such that in response to reception of an action request from the first client computing platform requesting an action of the second action type, the action of the second action type is implemented in the instance of the game and the amount of resources of the first resource type controlled by the first user is reduced by the cost of the action of the second action type, and wherein transmission over the network is initiated to the first client computing platform of information that causes the first client computing platform to present to the first user a result of the action of the second action type, and the reduction in the amount of resources of the first resource type controlled by the first user.
