If anyone is interested in trying out a PBEM game of Civ4, I'm hoping to start a game of this some point this week.
To that end I've started a post for players over on the strategy forum on boards.ie.
So if you're interested then either reply here or there I'll add you to the list and we'll kick off once we get 4 or so people available to play and try and have a turn running once a week.
The game will be using the lastest patch which at present is 1.52 (you can get it here).
Once the PitBoss server is released I'll hopefully run one of those which should easy the playing of these sorts of games.
