Since i live in it: America
IF we go by the British:
first they landed at Roanoke and Jamestown. Jamestown was successful.
#1 expansion: colonists were given the right to move all the way up to the Appalachian mountains.
#2 expansion: When the US bought the Louisiana purchase
#3 expansion: The successful revolt of the Texans
#4 expansion: Mexico succeeds most of their northern lands.
#5 expansion: Gadsen purchase: brings the US mainland's border too today.
Many difficulties include:
1) no good maps
2) hard to make livings
3) Indians, robbers, etc
4) diseases, exposure, etc
5) ran out of supplies
6) broken down wagons, etc (if they took the boat to California, it will be: traveling for a long time, etc)
7) etc etc
hope this helps
