In WoG there is a function where additional monsters of various levels are added to neutrals depending on the day of the week. The funny thing was that, for example, in the 10th month of the game, say, about 500 Black Dragons join 14 Gremlins =)
I really liked Varg-Nar's story because I sometimes won like that myself.
/offtop/ By the way, I incredibly love fighting with tiny armies, and my favorite campaign in WoG is "A-d-v-e-n-t-u-r-e-s"; there on the first map—you probably know—the hero walks with one Knight, and a maximum of 3 people (halberdiers) join him in the middle of the game, and otherwise occasionally one unit at a time during the process. A very interesting thing!
