I think even the option of tactical battle would blur the whole idea of the game. To me it seems that an emphasis on the gathering of prestige requires strategic and not tactical planning. Granted, certain Kings rode out in battle, but that's the exception and not the rule. Indeed, I wonder if the King who led his troops into battle did not tarnish his prestige? I mean, prestige is a matter between monarchs (right?), and I don't think they'd take too kindly to bellicose (and dangerous) examples set by their wayward peers. I hope I just made sense, it is rather late.
