There are at least two more on 1km1kt.net - "Eastern Front" and "Lone General". They are the first and second 24 hour games I completed respectively. As you might imagine, the former is a psychology themed WWII game. Meanwhile, the latter is a solo war game.
I also entered the Game Chef challenge in 07, and that is floating about somewhere, under the title "Overthrow". Its odd in a lot of ways - such as your actually playing factions in a revolution, not individuals, - the GM ("el Presidente") is an antagonist to everyone, and one of they playing resources is money coated with a memory erasing toxin - so you can spend it for supplies, or use it on others to stop an action by making them forget what they were planning - though it enriches them at the same time.
Oh yeah, and a one page war game about pirates over on rpglaboratory - "Days of Plunder"
