Area 6

There are a few small walls in this Area, but the biggest one is at cq money. At points that you are not at a wall, progress is usually fast. If you hit one of those walls and are on a town that is a multiple of 6, you will likely have noticeably more difficulty going west. (You get more settlers than pioneers on those towns percentage wise compared to other towns, and the settlers give a smaller bonus in later towns. The targets are also higher, meaning it will take more resets to get past them if you don't have lots of patience.)

This article contains a list of all business upgrade bonuses as well as milestones for upgrading all businesses of a town to a certain level.

This video shows the complete list of cash upgrades and pioneer upgrades for this Area.

Area 6 is similar to area 5, with the main differences being that some all profit pioneer upgrades are even lower than in area 5, and that the cash upgrades are very similar to those in area 5 (and therefore area 2!), with the main difference being that the cost of area 6 cash upgrades after the starting ones is about 5 million times higher than in area 5, and everything else is somehow balanced accordingly.
