Non-playable character

NPCs (Non-playable Character) are usually non-playable sims in both The Sims and The Sims 2, but it is possible to play them through the use of Mods.

There are two main types of NPC. Ones that through relationships and simple cheats will be able to be playable characters without any programming errors and ones that were specifically not meant to be played.

Sims 1 NPCs
Sims 1 NPCs were very limited. The could only be interacted with concerning the job they were doing, e.g. the dog trainer could only be interacted with to train. There was one NPC per job, who wore the same uniform, with the same face and names such as 'one sneaky sim' or just 'the maid'. They couldn't be killed, married or move in. There was no legit way to get their outfits.

Sims 2 NPCs
Sims 2 NPCs are much more colourful. For starters, basic NPCs could be talked to, befriended, married (among other things). Each had a different face, hair colour and name, there were male and females and they made more logical decisions, mostly.
