I've been a fan since Sims 1 (Hot Date), yo! :D
Sims 1: I've loved this one when I was younger. It's aged okay, and it can be difficult to take care of their needs (to the point of me using needs cheats sometimes), but it still was a nice game. Lots of good content, and it introduced me to the world of Sims. I rarely play it anymore, but I would put it above Sims 3 in terms of overall happiness and satisfaction.
Sims 2: LOVED, LOVED this one! This is NUMBER ONE, for sure! This one opened the Sims world a bit, and added sooooo much cool new content. I love the retail and business stuff! This game is still very good and can still be addicting at times, but the loading screens (which are long for me, for some reason) and the lack of oceans and mermaids and limited supernaturals is starting to get to me. I still play it from time to time, and it's still the number one Sims game for me, though Sims 4 is catching up there.
Sims 3: It's okay. I'm mixed with this one. It has lots and lots of content, for sure, and beautiful big worlds and so much customization tools, and some great content. And yet... I... just can't get into this one as much as I did for the older one. I dropped it at base game and only picked it up and collected the packs in a sale about 3-4 years ago. It's ok. Love the CAS and CC and mods. But... I just... can't get into it. My sims sometimes ignore each other (and some of this continued in Sims 4, to be fair), there were no open restaurants until later on with a mod and a store item, no sewing or proper retail until a mod, my towns were still sparse in some packs, and my fairies kept going into their fairy homes to party constantly, and the supernaturals are somewhat dull. I played around more with the CC and mods than I did actually playing the game last year. Despite all of the content, I felt bored and frustrated for some weird reason. This was not even going into the technical issues I had with it, and my computer just didn't like this game at times, lol...
Sims 4: Oh, this was one was terrible with the lack of toddlers and missing content at launch time. I was also frustrated when my sims parents ignored their crying baby (which was an object). Once toddlers and vampires came in, I was feeling much better about the game. Parenthood, Kids and Toddler Stuff, and Dine Out helped a lot with giving me some good content. So I was happy again! :smile: I ignored some of the flaws and lived with some bugs, but I was feeling much more relaxed with this game.
There is a laidback feel to it. I didn't have to stress out like I did in past games, and I didn't have long loading screens. It was relaxing and nice to pick up and play for the short bursts of time I had to play. (I was having less time to play as an adult with college schooling and trainings, etc.) I grew to like the cartoony feel of the Sims, and I loved the toddlers.
Now, with Get Famous and Island Living, I feel excited again, and I continue to enjoy it despite its flaws. It's in second place, but it's getting close to becoming my favorite and most played Sims game at the moment. (My computer also liked this game better than Sims 3, which is a shallow plus, lol.)
I will admit: It's lacking in some areas, could use more content and more depth, and could better execute some ideas better, and it's buggy.
But I still enjoy playing it. It is the only Sims game I play a lot nowadays, and I want to relax with a Sims game, and this game does it for me.
I'm open to Sims 5, though.
