Hi, I have a question about mods for The Sims 2: why are they always tied to objects, unlike in The Sims 3 and 4, where they are interfaces?

Hi :) Well, not all mods, but I see what you mean. In Simantics, behavior is tied to objects, they run the show, that is how the game is designed, and that's the part of the game that attracts modders, when they want to change behavior of objects or sims. Modding is not limited to Simantics, though. Take lighting mods, or asi patches, for example. As to "why" - wait a sec I have a good one...
