id rather have fewer safe houses with more detail and access over many safehouses that dont serve much of a purpose. the hill-side house in the trailer, with like a 5 car garage, working lap-top, working stereo, hot tub you can sit down in, more enterable rooms, small features like turning the lights off/on, opening/closing curtains or windows, would be way better then 16 houses with more non enterable rooms, 2 car garage. its not the amount of safehouses that matter but what the safehouse is able to do, otherwise it is just plain old interior.
also varriation in setting. a hill-side house, a condo, bungalo(if thats how you spell it) beach house.
