TS3 simply because of the Open World.
Even tho I cant play it on my mac

Sims 3!!

I have many expansion/stuff packs so I didn't even bother with the Sims 4 because the graphics looked such a mess

What?? Why not

I think it's multi platform but even if it's not, if you make an origin account & have an online chat with their team they can "upload" your game to your origin account so you can play it on anything

They did that with my sims 2 games because I changed laptops & they weren't working on my new one, so I gave them the product keys etc (after they made me try loads of stupid stuff like turning it off & on again) & I just downloaded them onto my account

Gaming on my mac is miserable, the lagging is insane & it crashes within 20 minutes of gameplay so I sadly avoid playing the TS3 It just sits there on my desktop collecting dust alongside TS4

3 was dull, dry and boring. Sims 4 is much better

The Sims 3 was great, before EA decided that more content is important than actually making the game work.
My PC can run this lag free:





but drops to like 12fps when panning through this:




then sorry but no.

The Sims 4 is my preferred out of 3 and 4, just because it runs at like 90fps stable for me, and loading times are like 5 secs. It needs more gameplay at this point though.

I still play King Sims 2 the most. Just downloaded all the Sims 2 Store Content last week

And lbr: Sims 3 isn't aging well graphically whereas Sims 4 will at least look better for longer since its "stylized" rather than trying to look realistic.

Forgot to mention though, that the Sims 4 really does need toddlers. The game feel slightly empty without it.
