I'm not satisfied of the sims 4 too. To me, it seem a 1.5 would have been a better number instead of 4, looking at the gameplay in it. Is incredibly laking to me. :/ (well, not at difficulty...the sims 2 wasn,t an easy game...)
Expecially the life stages are just so...limited, and lacking... Is astonishing how many things less the game have looking at the sims 3 (base game!!!) and the world...is quite a big disappointmant, after playng the sims 3.
For the sims 4 I was looking for a sequel of the sims 3, and I didn't even found a sequel of the sims 2... :'(
