I switched to TS2 after TS4 and I'm not going back!
I started by creating my own sims, but eventually I wanted to get a feel for the premade townies. At first, I tried the Broke household and had an absolute blast! These sims are keeping me busy, and I love it. All the little details blow me away - I can't believe how much love and care went into this game. The sims feel much more real, and the interactions available are amazing.
Now that fall is over, I switched to the Calientes and married Dina to Mortimer. The wedding was absolutely beautiful - oh, how I missed the cutscenes! I used to play TS1 and 2 as a kid, but I barely remember anything, but this does feel very nostalgic.
I can't see myself going back to TS4 anytime soon, as it really is a terrible downgrade in comparison.
The only downside is that I can't get reshade to work - it crashes my game every single time. I tried a lot of the tutorials I found on reddit and that one RPC mod, but nothing helped.
However, that is a small price to pay for a truly amazing game!
