As for Fable 3, I thought it was too easy, the last part of the story basically tells you to save money and keep reduced taxes and stuff in order to be a good person or tax the hell out of the people in order to get rich the easy way... Supposedly it was hard to get all the money needed without increasing taxes, but I found it really easy simply by doing jobs and other easy stuff that gave quite a lot of cash, not to mention that since my character was loved in every corner of the land and owned all the buildings in all the towns, it was just way too easy...
Also, increase the rent of your houses didn't change your alignments so I could rip the hell outta the people in my mansions with the highest rent and still be seen as a saint.
