Always jumps to my mind when I am about to start Sims 4... with sims 3.. horses were in the "pet" expansion, additionally to cats and dogs... Sims 4 had no horses in its pet expansion.. and the hampster stuff is in an extra pack for extra $$$ (and they even held back some of the matching furniture, to have that in another pack), maybe there will an extra horse pack for extra $$$ in the future... who knows.. So the amount of content is getting really low in some parts of the gaming industry. It's all about the money for lesser and lesser work.
