I have a whole bunch of CCs. In the thousands but currently I only have two mods. The mods are the no relationship culling and the quick walking the dog mod. I prefer to keep my mods to the minimum and although I'd love to use the MCCC mod I really don't dare to.
The last expansion broke it something fierce (I've never had it installed though) and I did read that some people did loose their save that they had at that time. I really would hate to have to start all over :neutral: so I don't, at this time, dare to install it. That is also why my mod usage is quite modest. I do plan on adding a few more, for instance there are two custom careers I am interested in trying out. but it will never be more than maybe 6 or 8.
