I have mixed feelings about TS3 & TS4. Each of them have some things (or several "some things") that I like.
I've never been a big "player" of either game so I can't compare personalities, emotions, attractions, etc. because I mostly just built and decorated houses, and my favorite thing was to download all the fabulous CC from amazing and talented creators! It feeds my shopping addiction and it's free!
I used to play TS2 all the time tho and loved owning a beauty salon on my home lot and when I did actually "play" TS3 I either did the architect or stylist profession, so I was really disappointed that TS4's "active" careers didn't include something similar.
I was actively playing TS3 (aka ....buildling & decorating) when TS4 came out and the first thing that struck me was how bright and happy and cartoony the world looked ..... I HATED IT! I thought it looked like a child's game, not a sequel to the Sims series. It still, to this day (7 years later) sort of bothers me.
I like my sims games to look more realistic since I mostly decorate or build so in TS4 I have to use a TON of CC and default replacement textures for the ground, sidewalks, roads, world lighting mods, and reshade to tone the bright, happy looking world down to make the game look how I want it to.
In TS3 I didn't need a lot of CC because I could match everything with the color wheel and patterns.
The one thing I can say about TS4 is that they make a lot of nice plants, to me they are much better than what was done in TS3 (although the textures are very fake looking but it matches the art style they chose to go with for this iteration).
The first time I went thru the build/buy catalog for TS4, I was actually in shock by the size of the furniture and windows/doors, why does it all have to be so exaggeratedly over sized? And who ever thought that all those fake painted nicks on every piece of wood looked good? Just because a game is low poly doesn't mean it has to be thick and chunky! They HAVE improved a lot in my opinion with the last few packs as far as the look of the build/buy items, Tiny Living and Eco Lifestyle both have really nice furniture, it's sleek and more modern and the color pallet is soooo much better and the woods actually match!
I'm okay with TS4 not being an open world, but one of my pet peeves is how small the worlds are! There is one world that literally only has 4 lots and 3 of them have buildings on it! The other thing that bugs the crap out of me, is the fact that we can't even "edit" the world to remove things, like trees that are in way of taking a good screenshot. And, some of the worlds are so "themed", a lot of the houses on them are old style homes, which would be fine if we could bulldoze them and put down what we wanted, but we can't because they're FAKE! So it's really frustrating to try and build a neighborhood with similar styled modern houses and all of the dummy houses are from 1900-1920!
I like some aspects of the build tools in TS4 but not all of them. Like for instance, I hate having to delete the upper level floor in order to see the level below for example you want a hallway near the stairs to be in the exact same location on both levels, you can't see the lower hallway to match it up until you delete the floor. I much preferred the way it was done in TS1, TS2, and TS3 where you went up a level and it had grid lines and you just placed your floor tiles where you wanted them. I like the roofing system in TS4 a lot tho! And now that you can move the doors and windows freely is awesome! I don't like how you can only put certain trim on your house if your house is only utilizing short walls. They should be able to be placed freely on any height wall.
I hate that TS4 doesn't have curved pools and I'm floored that there's no actual diving board! There's a jump and belly flop thing, what is up with that! And we don't even have a water tool! So we have to make fake ponds with square pool edges and cover the edges up with plastic looking rocks and foilage. Again, I'm just floored at that and look how long it took to get terrain tools! All of these things should have been in the base game at launch!
I do like that in TS4 we can add a foundation and change the height of it while building instead of having to plan out the foundation in advance.
I absolutely HATE with a passion, that we can not change the ceiling! It's a hideous grayish/blue color that looks horrible on rustic/industrial builds! I seriously don't understand why we can't, a ceiling is nothing but a floor above the head, we could do that in TS2 and TS3, why take that ability away?
I love that in TS4 we can resize and raise lower anything and things on the wall can move freely. That is one thing I miss desperately when I go back to TS3! But I feel like the resize function could be a little better, like much smaller increments because sometimes you want to make something larger because it's not quite big enough but when you resize it, it's ginormous! And vice versa, some things just don't shrink well. But I'll take that function over not being able to resize at all!
The other thing that is really noticeable is TS4 packs just don't have a lot of stuff "to do". In TS3 when I would actually play there were all kinds of things for my sims to do or try, and so much more things for babies, toddlers, kids, and teens to do (I never played with elders so I can't comment on that).
TS3 had a lot of lag especially in Isla Paradiso and Bridgeport but I installed fixed worlds and NRAAs Overwatch and it doesn't lag at all now unless I'm in CASt for a long time, then I just go back to live mode and let it run and everything is fine again. The only time I had lag in TS4 was after my graphics card died while I was waiting on a new one to come, it would be a wee bit stuttery.
I create CC for TS4 because it's much easier to than the other games were in my opinion, but I still prefer TS3 most of the time.
If I could have these things I might be able to be completely happy with TS4
- CASt (with the ability to add our own patterns)
- Recolorable Ceilings
- Spiral Stairs (or something similar with a smaller footprint)
But since I know none of that is ever going to happen, I'm patiently (well, actually IMpatiently) waiting for TS5!
