@Kerem93 - I totally understand where you're coming from. I think for me, it's hard to pinpoint exactly where the game is lacking. But I will try to describe what I mean: TS4 everything is 'happy, happy' all the time. There's no real challenge in making friends, or even falling in love. In TS2, it was not easy to make friends and you couldn't just walk up to someone and have a romantic conversation if they weren't attracted to you. I miss random things happening, like in TS3, I recall a meteor falling out the sky and killing my Sim's child. I was literally shook, as it was totally unexpected. This type of stuff doesn't happen in TS4....again, it's so 'happy, happy' all the time. & then there's the emotions. TS4's selling point was emotions when it first was released. TS2 Sims had way more emotion than TS4 Sims do. If my Sims are angry, I want them to stay angry....not be angry for 2 seconds and then flip back to happy because of some moodlet. If my Sim's spouse cheated, I don't want them to be able to hug right in that moment. If someone died, I want them to be sad and stay sad for a bit (if it was someone they had a relationship with). If two Sims fight, I want them to be mad, not just hug it out 2 seconds later.
The stuff I mentioned above is what I mean when I say that this game lacks 'depth'. I enjoy TS4....I play it, sometimes I find myself getting lost in my gameplay. I do like how the Sims look, and the graphics and how the game runs on my machine. But I do not play this game without mods. I play a heavily modded game in order for me to enjoy it. TS2 & TS3 I didn't ever need mods. But I think what's challenging is that with each iteration, I think the Devs will have more of a challenge to come up with new content + old. It's finding that balance as players want both. It was probably easier going from The Sims 1 to The Sims 2, as you only had 1 version to compare to, so TS2 was a major improvement. But I think as time goes on and you have all this content to compare/contrast to, it's always going to be this major challenge to make the next iteration bigger and better......where the benefits outweigh what doesn't carry over from the previous version. I think that's where TS4 missed....there were no major benefits in the base game to outweigh everything that didn't carry over from TS3, so it just felt like this huge hole where things are missing. I think has gotten better since it was first released, but IMO, this is why I feel the game is lacking.
