Thanks gents, I like the suggestions. Sounds like it could be something fun to play around with in the future. We are usually less competitive, so the throw back idea by heroes might be a popular comedic option. For now I'll just keep it simple (grenade) while we learn the game mechanics.
As for figures, I'm still painting them. So far the Brigade Games figures have been my favorite for Villistas. I will be using Old Glory figures for both revolutionaries and regular government troops too. The revolutionaries will also have some Artizan and Dixon "old west" figures mixed in since some of the Indians involved preferred to stay in their more native dress.
Thanks again,
Rod
