What rules do you plan to use?
Not sure to be quite honest, but I'm leaning towards 1871. The unit level I want to play is regimental. I've looked at a number of different rules, but I can't say for sure.
Overall though, I'm not too bothered as I am more a collector than a gamer. That is not to say that I don't like gaming, but the opportunity is very limited where I live.
BTW!
Thanks for all the great comments. I really appreciate them.
