Methods and systems for continuing to execute a simulation after processing resources go offline

A system for simulating a gameplay of a video game with non-player characters (NPCs) in a multi-player gaming network, wherein the multi-player gaming network comprises a plurality of end user devices each adapted to be used by a human player and wherein the plurality of end user devices are located remote from each other, the system comprising:

• at least one game server in data communication with each of the networked end user devices, wherein the at least one game server is positioned remote from, and is distinct from, the networked end user devices and is adapted to host a video game, and the at least one game server is adapted to:
• conduct the gameplay of the video game using the plurality of networked end user devices;
• determine that one of the plurality of networked end user devices is no longer available to conduct the gameplay of the video game;
• generate a specification of one of the NPCs based on a latest known state of said one of the NPCs executing before the one of the plurality of networked end user devices became no longer available;
• identify a replacement networked end user device;
• use the replacement networked end user device together with the remaining plurality of networked end user devices to conduct the gameplay of the video game;
• provide the generated specification of the one of the NPCs to the replacement networked end user device;
• continue to conduct the gameplay session including a simulated gameplay of the one of the NPCs;
• and
• transmit to each of the plurality of networked end user devices and the replacement networked end user device, the simulated NPC gameplay session, including the simulated gameplay of the one of the NPCs from the replacement networked end user device.
