They have comical moments, but each game has very serious main plots. The first game Shulk is constantly haunted by what happened to Fiora throughout much of the game. X is dealing with Earths annihilation and the pending doom of humanity. 2 deals with the Blade/Driver dynamic which leads to a lot of misery after drivers eventually die and the Blades are left missing them. There are lot more than those.

Xenoblade is way more serious than DQ, probably less serious than FF7, more than FF10, and maybe about on par with FF9.

I don't like the feeling of playing the same thing over and over, so I think I have enough of current DQ formula. They are good games, but they are predictable. As for Final Fantasy, I understand the criticism behind the lack of turn based combat, but the vastly different setting and gameplay they present in each generation always bring different crowds. Since Final Fantasy VI each Final Fantasy has its own identity and is a complete game and universe from start to finish, Square is the only publisher that have the balls to use their biggest IP to spit in whatever their fandom wants and do whatever they feel they need to release and I find that... I don't know... dauntless I guess ? I hope they never change their approach, the market needs more games with Final Fantasy design and philosophy

And FF XV sold almost 4 million after PC release. One thing is to delay the game for many years like Atlus does with Persona, but a one year timed exclusive? Have it hurted the sales of any game at all? 

Xenoblade games can get pretty dark at times, with allusions to genocide, slavery, suicide, bigotry, etc as well as seeing characters being stabbed/impaled and the like.

It's no TLOU but it's definitely mostly serious.

The games have very serious plots they dive well into elements far more serious than most other JRPG it's on par with FF on seriousness, the execution is akin to FFVI where even though the game has lighthearted moments the are also very serious moments.

Nintendo's trailer is in 1080p and it looks either native to me (except low texture resolution) or at least some very good temporal AA, better than AMD FSR. It is hard to say bc artifacts could be yt compression. Frame rate seems to be locked at 30fps (trailer is 30 only). I can see advanced techniques like per object motion blur and adaptive dof. It this all runs at >720p 30fps (as the trailer implies) it will be a miracle game for the Switch.

More than 720p native, no jaggies to be seen

Selective motion blur (and a lot of yt compression)

Xenoblade 2 already used temporal AA, depth of field, and per object motion blur, so seeing these carried over to Xenoblade 3 and perhaps further refined isn't surprising.

If this was a Switch 2 game, the image quality, textures, lighting, shaders, geometry, and general detail density should be significantly higher.

This looks like the kind of step up over Xenoblade 2 as I'd expect to see comparing a game from a system's first year with a sequel coming out in its 6th year. They've had more than 4 years to get more familiar with the hardware and optimize their engine.

As far as the trailer resolution, sub-1080p games often have 1080p trailers on Youtube.

Golden Country is about bullying one of your companions to death until they get grilled and roasted. 

It is possible the game is using FSR. If the recent reports about Nintendo using FSR and the technique's capabilities are true then I expect Nintendo to be able to squeeze even more performance out of the Switch going forward. And using it could help Nintendo prepare for effective use of DLSS for the Switch 2. I wonder if this can be patched into older games to help them look or run better,. It would be great if Doom 2016, Wolfenstein 2, or Witcher 3 could be made to look sharper while having a framerate basically locked to 30 FPS.

From my very limited understanding, they have similar results but entirely different ways to get there, FSR and SS. SS uses AI, FSR doesn't and does something else.

Switch is my favorite console but I just didn't like Xeno chronicles nor did i like X. The battle system is meh. I wish I cared about the franchise.
