Was kinda fun...
but with the auto fire on all I was really left doing was moving my mouse around, which was kinda balanced by the "reinforcements" that just got in my way.
Without any true reason/need for the those extra allies to be there (since I could solo the armies myself) it didn't really make sense to add them in, except for forcing the player to turn auto-fire off, which wouldn't be a real reason in war.
Some extra features like upgrades or just about anything else to make you want to advance to the next level would be nice.
