advice: what is the best Tiller game?

[Philippe]

At the risk of sounding like an echo, I think the best way to approach it is to pick a game that covers a topic that you're especially interested in. But keep in mind that many of the games will feel very different (even though they have the same rules) because the situations they portray have different characteristics. So if you want to play a blitzkrieg panzer assault you're probably better off playing Smolensk than Normandy.

Apart from that, my current favorite (and it's been my favorite since it came out) is France 1914. It uses the same basic engine as the Panzer Campaign games, but because of some subtle rules differences has a totally different feel. A very elegant piece of work that really makes Barbara Tuchman's Guns of August come alive.
