Who is 'they'?

The original game (but not CoH) is cleverly designed to be entirely playable with just four inputs, all non-movement actions can be performed with two simultaneous inputs (jumps). So it's entirely playable on a dance pad that way. I haven't tried it myself, but I know it's a thing you can do, and there's footage out there of speedrunners doing dance pad runs.
Every headline from this site is like this. Utterly shameless.
-
Cadence of Hyrule - The original Crypt of the Necrodancer is one of my all-time favorites. CoH doesn't quite reach that incredibly high bar, but it's still an excellent game in its own right.
-
Metroid Dread - Hits all the highs of Super, but with greatly improved combat and bosses. So yes, I am calling this better than Super, you heard me.
-
Puyo Puyo Champions - Technically, this is not exclusive. However, I am counting it as such because the online playerbase is dead on every other platform. If you want to play the greatest competitive puzzle game ever made, the Switch version of Champions is really the only option.
-
Splatoon 3 - It's Splatoon. It's the newest one. It's good.

Pluto is highlighted on Modern and is not highlighted on Traditionalist.
Zelda also sells like hotcakes, and yet they still put effort into that one.
If you asked me this question a month ago I would've said Azumanga Daioh and Yotsuba&.
The fascist in front of the curtain is loud enough already.

The purpose of federation is to build a network that no one entity can control. An evil CEO can enshittify their own server, but the damage they would deal is limited to their server. The rest of the network would still exist outside of their control, and users can easily leave their server to go elsewhere.
Is that something I should be apologizing for?
