BTW, as it doesn't need to get global state of the tangle for the node, so is the tangle possible for decentralized game?
Some players may not see actions of others in time. Not sure tangle is good for games.
Is that because of the network being fractured?
Also, is there a rough estimate of how long a transaction must be in the system to be considered more or less final?
Like in Bitcoin, there is a 3 block confirmation time and a person can be reasonably assured that transaction won't be reversed.
