One thing that's always bugged me about founding settlements is that the game gives you a "minimum" 2 food + 1 production. This basically makes settling anywhere that has food on it useless. Hills being really the only place to settle (for the extra production), preferably a hill on a river (extra production and gold). What I'd like to do is change this to add 2 food and 1 production instead, allowing much broader choice in where to settle.
