Recently I have been doing little figure gaming but have been playing the following:

Embrace an Angry Wind by The Gamers [Part of the Gamers Civil War Brigade series game 1-07]. It has a great solo scenario where the cream of Hood's Army of Tennessee marches to its death at Franklin in 1864. I used it to familiarize myself with the Brigade series of games. The army already has its orders so the player can concentrate on movement and combat.

Blood and Iron, The Battle of Koniggratz 1866 from Command magazine Issue 21. It is brigade level and the mechanics are simple to understand. The main difference from ACW games is that artillery is much more powerful and has a range of several hexes. It is an easy game to manage as the stacking limit is two counters/hex and only then if they are from the same corps and not cavalry. Again, with the Prussians attacking and the Austrians defending, it is an excellent soloing experience. Taking place only a year after the ACW it was the type of "decisive" battle that commanders expected First Bull Run to be.

Blood and Iron plays easily and different scenarios are given to expand on the basic situation--these usually favour the Austrians as in all the full battle games I have played the Prussians have won. The short learning game featuring the fighting early in the day is, however, very difficult for the Prussians. This is because only part of their army is up against the entire Austrain force.

Kolin by Clash of Arms Games. I am looking through the rules and slowly playing through the learning scenario. It is battalion level and the components are superb. I was about to to say that they are the next best thing to figure gaming but I must correct myself- thay are at least as good as figure gaming with very wellpainted figures on sculpted, period terrain. They strongly evoke the feeling of warfare in the 18th century. The system appears more straightforward than the Gamer's Civil War Brigade system. In fairness to the Gamers, Kolin is simulating small professional armies rather than the great spectrum of men/equipment types that fought east of the Mississippi. I will let you know more when I have played the system through a few times.
