PLEASE HELP IM NEW TO SIMS 4

I'll grab a few more questions...

5) What is an expansion pack and are there any that is free? Or isnt so costly?

I'm not aware of any that are free except the mobile version. The game is much more involved and better than the mobile version, though. I  addressed expansion packs in the other post you made, if you would please reference that.

6) I know this question is going to sound stupid but can I download The Sims Seasons expansion pack and use that to play the game or do I need to actually download The Sims game and then I could download the expansion pack later?

That is not a stupid question. None of the expansion packs will be usable without the base game ("The Sims 4"). For instance, I initially purchased "The Sims 4" to see what it was like (I had played 1-3 years ago), and to confirm whether or not I would use it much. When I found I enjoyed it a lot, I gradually added expansion packs, which is fun to do gradually as the 'story'/play unfolds and grows gradually doing it that way. Also, they occasionally put various expansions on sale, so that is when I add them.

7) what's the difference between Sims FreePlay and Sims mobile?

Sims mobile is REALLY simplified and constrained compared to playing on a computer or console, at least when I tried it several years ago. Not sure about Sims FreePlay.

8) what's the difference between Sims 3 and Sims 4?

That would be better addressed by others since I did not play my Sims 3 for long. I found it to have less personality than the previous versions and for some reason it did not jive with me. But... when I got Sims 4 I loved it and have been playing it a lot. I think it helps a lot that I have a computer that can handle the game this time.  🙂 Sorry, not a useful comparison since I have no specifics, but I'm sure someone will explain this better.

Hope that helps a bit. If you get the game I hope we will hear from you again! 🙂
