Here's an interesting limited deployment game we just finished:
https://www.warlight.net/MultiPlayer?GameID=9000249There were a couple of violations of the deployment limit, which we dealt with by having the player surrender, and only allowed to continue playing if he offered a concession to his opponent. (Usually giving up a certain bonus.) This worked well enough. For 99% of the game, however, the limit was observed accurately.
Some interesting features:
There were a few carefully-planned invasions, like my takeover of the Southern peninsula on turns 28-30 (my opponent's production was not that much lower than mine, but I was able to surround him and remove him pretty quickly) and Ezoroth's gambit in assembling a large army on the island at the North of the map and then trying to mow through my defenses. These are interesting moments which reward careful planning.
Also, take a look at how borders develop during the game:
Each player has enough deployment power to hold a border of a certain length. Open a larger front with him/her, and they cannot defend it all (unless they prepared in advance).
This creates an incentive to surround the opponent, as that can give you a deployment advantage.
On large fronts which can be fully reinforced by both sides, the battle is slow and very tactical - minor victories and defeats accumulate. You must choose between leaving weak spots in your line and assembling larger armies in order to break through your enemy's. Very satisfying!
