I did the same thing. It may have been because there weren’t as many dlcs and expansions, but it just felt really dull. Plus it didn’t have the completely open world like 3 did. Sitting through all those loading screens every time you wanted to go somewhere was a pain.
Sims 3 has the most hours played in my steam library, but I haven’t played it recently. I seem to go in cycles where it’s all I’ll play for a few weeks, and then I won’t touch it for several months, and then I’ll come back to it again. It’s a great game to have mindless fun in, and last I checked, the mod community was still going strong.
