I know the title says MMOG, but I must have been some of the few playing. It's good to know about the numbers. I can see some balance issues where a player can just run to a high number and take it over.
What happens if a player modifies their code as another is trying to capture their node? Or what happens when two opposing players try to capture the same node?
The more I've thought and played it (it's still on my system), the more I wonder what happens in the long term. I think it's a great concept and I can easily see this being a viable game that can make money one day, for sure! But I can also see that if a new player joins after all the nodes are captured, they'd give up trying to even get a single node. The Mastermind game take a while, and I can see people trying to get a node the first time before giving up and uninstalling it. I am not saying it's a problem, but something I can see happening with the degraded attention span.
