Re: Laptop for 3 & 4
@Wixomrie Sims 3 doesn't require more than an Nvidia 1050 ti (mobile) or regular 1050 (desktop) to run on ultra settings. Even with a lot of high poly custom content, the game will still run on ultra on a 1650, or perhaps a 1060 mobile. Sims 4 is still in developement, and of course future packs might be significantly more demanding than the current ones. But a 1050 will run all current packs together on ultra settings. The way the game has developed so far, it certainly seems like even an Nvidia 1660 ti would be overkill for Sims 4, not that it's a bad thing.
There are plenty of computers with dual hard drives, but there are a lot more with an empty slot for a second hard drive of your choice. Are you willing to get one of those and add that second drive yourself, or have a store do it? If not, that's fine; it just narrows things down somewhat. There are far fewer options with a 2 TB HDD, if you really want that specifically, but I'm sure I can find a few. And in your price range, you really can get almost whatever you want.
All these laptops have reasonably pretty displays. IPS is the highest quality screen, and almost any gaming laptop other than the very cheapest options will have one. Of course, not all manufacturers' products are created equal. If not for the current situation, I'd suggest you go to a physical store (Best Buy is always a good bet) and have a look at the monitors, especially if you can find a few gaming laptops. You might find that you like the look of, say, MSI and Asus screens, but not Dell or Acer screens. That's somewhat subjective though.
If you're not sure what you like, try to think of screens you've thought looked good, or any you didn't enjoy staring at, and list them. I'll try to find valid comparisons to current laptops and sort them that way. Or, if you really have no idea, I'll just find the ones with well-reviewed screens and go from there.
