Oblivion and Skyrim are 200 years apart, but geographically border each other. Classic Oblivion didn’t render Skyrim, but that was more for technical reasons than anything else. If you get high enough up in Skyrim on a clear day you can see the entire continent.
It’s also from the era when people were expected to read the manual while the game installed, so the game never has tutorials for certain things, most prominent being fatigue. New players tend to run everywhere, drain their fatigue meter, and struggle to hit anything or cast a spell. Just reading the manual, as the devs originally expected, solves a lot.
Also, Skyblivion will, at worst, only cut into their PC sales. The official remake will be the only option available on consoles due to the nature of the mod.
Kingmaker also has the problem of every encounter being designed for a full party but not actually having access to a full party until late in Act 1, after many mandatory combat encounters. The RNG also seems to hate me.
Uh, enemies are actually less bullet spongey on high difficulties, just like the player. Some humans have armor that you have to either spend bullets shooting off or shoot around by aiming at unarmored portions, but enemies typically go down really quick.
Turn based tactics or 4x games would absolutely benefit from both, and the touch screen. Being able to play Fire Emblem with any of the three depending on what’s comfortable at the time would be wonderful.
Even then, it’s not a full stop on incompatibility, it just means that you need to own Switch 1 joycons to pair to the system instead of using the new ones. So you can play Ringfit on Switch 2, if you have the old joycons and a way to charge them.
Same with Paradox games. 4X in general is just really hard to get right on release because of how many interlinking systems there are, so waiting for balance updates at a minimum is never a bad idea.
