scissors/paper/rock is a nice thing - try adding one or two more .... items into that theory - and the problems start.
we have
fighters
bombers
gunboats
destroyers/cruiser
battlecruisers
battleships
its much more complex than 3 classes. although its of course clear where you re coming from, its not as easy to balance those 6 classes. furthermore, the scissors/paper/rock theory suggests that all of those items are "worth the same" - which is not the case with our ships. - a fighter is not worth as much as a battleship.
so when we apply the scissors/paper/rock concept, we d have to take into account that - when you do the scissors, you have to pay 10 cent, when you do the rock, you have to pay 10 euro and when you want to do the paper, you ll have to pay 50 euro. so when you re poor, all you can do is the scissors... .
