**LOW Army Cap Game**
Link to a custom, but I think you can put in similar elements to mix it up. What makes it interesting is the low army cap. You need other tweaked settings to make it playable. Below is an example that I think makes for an interesting game.
Army Cap: 2.7 (This is very low!)
Armies per Territory: 1/3
You need to ensure that the neutrals are low (0) and you have enough starting armies to get the first bonus, or you can supplement with small and frequent reinforcement cards.
You will often find yourselves constrained by the cap, so judicious use of your armies is very important in attacking and getting bonuses. You essentially are penalized for having most of the bonus.
In this case, if you have 8 armies taking up 9 of the territories in the bonus, you don't get the bonus to increase your income and thus the cap, and you have 8 armies doing nothing for you. When you get the last piece of the bonus, your cap goes up by 2.7 * Bonus value, so you get an extra 15 armies the next turn.
