It was released along side mods (a very slow first party mod manager) so I guess they think it makes it better. The mods are good and it's a nice thing that they don't depend on the steam workshop anymore but they don't excuse releasing a £10 dlc along side it that just adds more skins for low density houses when the game still doesn't work
They also made some pretty significant improvements to performance, and importantly, simulation speed with this one. But yeah, the DLC is kind of insulting.
