The Sims 4 has had me doing something that I haven't done for years, have that "just one more day" feeling, where I end up playing until about 5 or 6 in the morning, not noticing how time has passed.
For me, 4 is more like 1 and 2, where you can essentiaĺly just drop in and play (as opposed to 3 where after getting a few EPs, you essentially have to reorganise the entire town and set up infrastructure before one can play without feeling something is missing, that is what killed 3 for me).
