I would recommend the John Tiller Software games. Made by the same game maker that made the Talonsoft games in the 90's. It is a hexed based game. I like it because it gives me at least a small view into what it was like to move troops, the logistics involved, and fog of war. It is also alot of fun to join a game club and play other human players. I would recommend Wargaming Society or ACWGC.
