Is there a Updated Guide on installing mods for this game, like where do u even start first of all ?
Not on how to install mods, but what mods to install first etc. ?
Grab MCCC mod.
Grab Wicked Whims Mod.
Grab Nisa Perversions Mod.
Grab Devious Desire Mod.
Get Basemental Drugs.
Get Basemental Gangs (if you want)
That should be your core mod set.
From there -
Animations to fill in Wicked Whims and Devious.
Clothing to fill in your sims
Body items to make your sims look better
Building items to make your lots look better
Traits to add more traits
Aspirations to add more aspirations.
For NSFW Traits/Aspirations, see F95 Sims goodies (Your False Hope is the user you want to look up)
For Clothing - again F95 has you hooked up. (also SimsFind, TSR, etc)
For Bodies, Buildings, etc, F95 again as well as SimsFind.com, TSR.com and the interweb
There are a ton of additional mods but no need to bury you on day one. Once you get the feel for what you're looking for, you can hunt it down yourself. Or try out other mods that folks suggest but those 6 i listed are the core that pretty much everyone will use with the exception of perhaps Devious Desire and Basemental Gangs.
