Game 1: L makes a few mistakes, and Z easily wins.
Game 2: Z picks up speed boosts, logistics, and gloves, arrives on week 5, and captures an empty castle because L wasn't there. At the same time, Z enters L's visible territory and manages to defeat a couple of weak heroes in one turn and reach the empty castle.
Game 3: L is completely blocked in with two mines (no exits, no dungeons, no water, or portals). There's no mercury at all... it's impossible to build a guild. Z arrives on month 3 with skills of 23, 23, 20, 18 against L in the castle with skills of 6, 8, 8, 7. A total rout with equal numbers of troops.
Considering these three games, what would be a fair score between Z and L?)))
