Nah, when going for a culture victory the AI always leave it till the very end before attacking with a very big stack that they've been building up all game.
that's why i asked. the only cultural victory i've ever achieved without any war has been way back shortly after civ4 release with washington (nappy and liz as my neighbours) on prince level ^^ my most recent cultural struggle has been with the incan empire on emperor and with just the 3rd city like 2k points away from going legendary, nappy invaded with a HUGE stack of riflemen and took all of my cities within 10 turns Oo guess i'm not that good in diplomacy


and thanks for the write up kmad, always fun to read about other's games ^^
