I also agree, though if enough of the CPU values were exposed in configuration files, I think it could be made into something. I assume it is possible to make some blocks cost zero CPU in the configuration files and to control the CPU capacities of the various tiers. I've not looked at the configuration files to see. I do feel I understand how it works. I don't feel I understand how its implementation either (1) helps with specialization or (2) has anything to do with representing computing. I also see a marked difference between a multi-player game and a single player game. I completely understand how a multi-player PVP game might want Destroyers, Battleships, Transports, etc. I don't necessarily see how a single player game could lead to having a fleet of ships, unless those ships are going to be entirely AI driven and follow me around.
