The MMO model works because there is a significant amount of value in the product that never exists on the client. To use WoW as an example, all of the enemy spawns, loot generation, AI, spell scripting, etc all exists on the server. In the case of a single-player game like AC2, the only way to replicate that model would be to put AI, text dialog, persistence, etc on the remote server. This requires a tremendous infrastructure investment that just doesn't pay for itself in a non-subscription model. If the server just saves and restores game saves, I can mock that with enough input data. You have to have actual value on those remote servers that people will need access to.
