The time for pre-orders has come and gone. You can now order the 2nd edition of Sword & Spear for yourself from Great Escape Games. The rules let you play large battles set in the Ancient and Medieval periods. There aren't any minis specifically for the game, so you can use whatever figures you find most appealing. As long as they have equal basing, you're good to go.
The rules are designed to keep both players as active as possible. In some games, one player could go get a cheese sandwich while the other does their turn. Not so here. Each player gets a number of command dice that they then place on their units, which allow them different actions when the units are activated. There's a lot of strategy to where you place your command dice, as well as your choice in who activates when.
