I never really liked the Sims 2 as much as I liked the first game or any of the other games. It mainly had to do with the wants and fears system I really wish it could just be turned off completely. Wishes and whims are a step up to me because you could just ignore them. I also had and currently still do have a tone of technical problems with the Sims 2. It is very very easy to accidentally break your game. However, my personal opinion and the fact I think The Sims 4 is better overall aside, I do think it is definitely worth checking out the Sims 2 again. There are a lot of features that are unique to the Sims 2 as well as small details and fun random events that make it entertaining even in 2020. Sorak4 above me actually gave some really great examples. Also I will say Sims 2 University is done so so so much better than in 3 or 4. Just be aware it is a 10+ years old game so it is not going to look as nice and you might run into some technical problems. ,
