I want more realistic game play. Graphics can be crap in first version of the game as long as its bug less and really playable. So far in Guild 2 we start as pretty well set person with some gold able to start our own business. For a 19 years old person starting own business is pretty much not real.
I was thinking that maybe character we start with would work for other NPC's for some time and earn his money that way. Later would be able to rent his own working space for a shop or some factory (weak idea hard to avoid boring stuff like in the sims maybe - could be skipped). The more wealthy our family would become the more option would come. Buying land for our own factory, becoming independent. That would be basic starting scenario. Other way of starting would be getting our first ran down, poor health business from our father/relative. This would be birth of long term dynasty.
City's should be developed or developing giving more space to player. Renting / buying land to start our shop or factory first. Like in Assassins Creed opening blacksmith shops. Make giant maps like Morrowind with many City's / trade center. Even starting in small village would make player able to sell his good to a distant wealthy city. Nation borders and ongoing wars would have impact on business we open. Maybe player would be able to open. Sending prospectors out of towns to seek new mineral deposits and establishing mining business.
It's probably not possible for me to put all my ideas in the post, even less possible to make a working and attractive game out of it xD
It sounds more like The Sims, Guild 2, Assassins Creed Brotherhood and Capitalism+, Spore games all mixed up.
