My grievances with each game in the franchise

True. Perfection does not exist, and with something as subjective as a game, everyone has a different idea of what's great and what sucks.

I don't think I can list every grievance I have, but off the top of my head:

Sims 2

• The inability to travel between neighborhoods (same applies to 3)
  
• You could not have multiple saves, and finding the files was very difficult
  
• The loading screens were long, and this is a game I didn't mod
  
• Only two body sizes: thin and fat. And fat is really just pudgy
  

Sims 3

• This one is my favorite, so not many, but my biggest disappointment with it is fairies from the supernatural pack. I love mythical creatures and fairies happened to be my favorite (blame a show called Winx Club for that), so I was really sad fairies are limited to little more than pranks. Yes, it's closer to fairies of folklore (in most old tales, fairies are seen as tricksters at best and downright evil at worst), but I think they could've done better while keeping in line with making them pranksters.
  
• Another I have is the curfew. I modded that out.
  
• The forced maternity leave, though I don't recall if this was in Sims 2. I use Nraas. Sometimes, I allow it. Sometimes, no.
  
• Inability to cancel some actions, like scolding
  

Sims 4

This one is my least favorite. I still like it, but it's the one I have the most grievances with.

• It's too bright. And it's not a case of issues with my screen.
  
• I don't like the graphics/art style for the sims in this one. For architecture and objects, it doesn't bother me, but for sims, I don't like it at all. Weird.
  
• The emotions are too finicky. I've had sims change emotions three times within a minute.
  
• The snow. Petty, but I miss it being (kind of) deep.
  
• The size of the worlds, and that the majority of each world is a backdrop.
  
• Apartments. I didn't really like this in Sims 3 either, but at least, they could be placed in any world (unsure if the same applies to Sims 2). In Sims 4, they're restricted to San Myshuno.
  
• That it's ridiculously easy to build skills. I alter my sims' skills a lot because they somehow always end up skill points in something I just don't care for them to have.
  
• That sims automatically sit down or go into a group chat. I think this may have been in 3, but I don't remember it being as prominent (and I play 3 a lot).
  

And for all of them: aliens. I've never liked aliens. I know I said above I love mythical creatures, but I didn't say all mythical creatures.
