Actually, I would like to ask, how they can be seen. It is interesting to look as pass fights at rivals

I'm not sure what you're asking ... do you want to watch combat animations between two other civs?

Yes, I mean it. I could not understand as it to make. In my opinion it is impossible.

The only thing that I can make.
" Menu (main) - Advanced - Options - Game - Show Enemy Moves. "
But, I see only Moves, instead of Combats.

Changes are reflected here
c:\Documents and Settings\_user_\Local Settings\Application Data\My Games\Beyond the Sword\Profiles\Default Profile.pfl

The bit is exposed only "0" or "1".

The menu option is to show enemy moves within your line of sight. It doesn't show them ALL. If you have line of sight on everything, you'll get to see all moves, but be warned: your turns will take forever to process!
