I have a few different ideas how to prevent games that are several hours long. And also different ideas on how to trigger those. I would like to use this post to discuss them before I hand in a suggestion.

When should those system activate?
I see 2 ways to trigger this.
1.1) Activate after a certain amount of turns for example turn 30 this starts to function. This number could be adjusted via settings before the game starts. The upside is that it works independent of turn timer, so low players don't reach it in the early game.
1.2) Activate after a certain amount of time for example 90 minutes. Also adjustable. Slow turn timer would reach this earlier in terms of game state, but it could always be set to a higher number. -
What does happen to the game to not stalemate or end faster?
I suggest a sudden death mode. And here are 3 ideas how it could work.
2.1) Buff the attacker with up to 1 more dice to roll. This will increase the attackers advantage even further, and force player into action.
2.2) Nerf the defender to always roll with 1 fewer dice but always at least 1. I word it that way to include caps.
2.3) Troop decimation. Every turn after the threshold has passed 10% of all troops die at the start of each turn (rounded up but never kills single stacks). This would combat the too slow troops gain in prog caps.
I'm not too sure about the math of all of this, but what do you guys think?
