I use to play this game, and I used to be a well known online pigeon fancier...
But it got too popular and crashed.. When it restarted the fun was over for me, all my pigeons were killed...
More information from the website:
Welcome to Roekoe.be, the virtual pigeon fancier simulation. This slightly crazy game focuses on the activities of a pigeon fancier: creating a team that can perform in all sorts of situations by selling and buying, coupling and watching your pigeons having fun together before raising the young. Choose destinations to fly from to fill up the calendar, let those feathered friends fly and — eventually — die, and much, müch more.
But no pigeon fancier without pigeon fancier pub: Roekoe.be is also committed to its community. By using the forums or even the chat box you'll always find someone to talk to for a while and perhaps you'll even come across one of the developers. Since the official start on 1 september 2006 thousands of players have already explored Roekoe.be. You can be one of them too! Roekoe.be is completely free to play and the only thing you need is a web browser. Have fun!
