Gameplay mods make changes to the actual game and how you play it.
| MC Command Center | allows you a massive amount of cheats and other controls, such as editing an existing sim in the CAS, skipping them ahead for promotions, the frequency of townie pregnancies, force starting or ending a pregnancy, etc. |
| Wicked Whims | allows sexual animations and more control over who can have sex/woohoo. allows polyamory and multiple marriages. |
| Wicked Perversions | adds on to wicked whims. |
| Cosmic Gender Ray | this
mixes up gender presentations of random (townie) sims. |
| No Glo | improves
the lighting in your game. |
| Waist/Hip Slider | female sims only. |
| Enhanced Butt Slider | all sims. |
| Stand Still in CAS | |
| CAS Overhaul | |
| All Beds Give Same Stats | makes all beds have the same energy, comfort, and stress relief stats. |
| Already Upgraded | makes it so all appliances are already upgraded. |
| Always MOO | allows you to place items anywhere in build mode (there's a cheat for this, but this forces it on automatically). |
| TestingCheats Always On | enables testingcheats, which means you can shift+click on your sim to reset them (if they get stuck) among other things. |
| UI Cheats | makes it so you can activate cheats by clicking the UI, i.e., fix needs just by clicking the corresponding needs bar, auto-level skills by right-clicking on the skill bar, etc. (Patron link, but free download.) |
I believe most stuff is here compatible with the base game, but make sure you double check!
