i think by "win" he means break the stalemate. the ai in that game sucked and only stayed competitive by cheating. he should have been able to wipe out the opposing civs after 10 years of playing. especially since the op said he was only playing at prince/king difficulty.
First of all the game was technically won thousands of years back but he kept playing. And now they are in a stalemate that no one can break.
His thread is basically all about asking for help (and fresh ideas) to end this.
