I've been playing M2TW since release, and I just NOW noticed this:

In my Russian campaign, I noticed two tiny little crossed swords near Kiev. At first I thought it was maybe a resource I had overlooked (blades? lol), then I hovered my cursor over the swords and lo behold a window popped up telling me this marks the site of a great battle (between two other factions no less).

I honestly had not noticed any of these markers before in this and other campaigns (and I don't think it was covered in the manual...dunno - it's been so long since I read it).

Truly a nice touch from CA to make the campaign (and the map) feel more fleshed out. Was this little detail in RTW as well? Can't recall...it's been 2 and a half years since I played it.
Cheers.
