Battrick » Regions » England
When you registered, you chose a region in which to play. The only effect that this will have on your team is the weather. But even here, the weather is random, ie it won't always rain in Lancashire!!
It may well be somewhere that you have an affinity for, or just somewhere that you thought it would be nice to set up.
The regions that have been selected for your choice are the first class representatives in their countries.
