That's more because a) I'm on an island, b) it's a huge map c) I have only put 2 civs in the game (me and Brennus) and d) I have the Great Wall, which effectively allows me to not really worry about a military. In a normal game, it would be different story because I might have neighbouring civs (and a low power rating to boot). Oh, I'm also financial, so I can get away with teching with only 3 cities, for a while at least anyway.Game-wise; if he isn't needing to build anything but settlers and galleys
Oh well, FUN!
So, I wouldn't call it game breaking, more just that I set up the map to make it really easy (so I can see what it's like). It's like a fun colonisation game. I'm really surprised they didn't make a scenario/mod about it.
