I recently played in a game of Carnage & Glory. Each player had to give pertinent data to the GM who entered it into his laptop and reported results. As the game went on, players attention wandered. Some couldn't recall if they had already fired this turn. The GM had to check, etc.
The single point of data entry slowed the game down.
I read something about a guy working on a system of linked tablets, so each player could enter data called Electronic Brigadier. It is on Facebook, which I avoid for various reasons. Also, the last post there was in 2015.
Victrix is working on a platoon level WWII game that runs on an iPhone. I have an Android.
Anyone else know of commercially available computer moderated systems? Hopefully that don't require advanced study to operate?
