I'd go so far as to say Switch's 2021-2024 beats its 2017-2020.

What kind of games are you into?

Most of the best ones have been mentioned, but I'll throw in Lunistice as one of the best 3D platformers of recent years.

Oh and it's super cheap. I'll keep it in mind for sure. Bayonetta 3 is my number one priority now, love that franchise and had no idea, it showed up on none of my outlets. 

Alas, you can't beat Fire Emblem Three houses, Astral Chain, Mario kart 8. Fire Emblem Three houses alone makes it the best half imo but I guess it's preference. Bayonetta 3 alone might make the second half the best for me though 😀 ... I fucking love those games and it's my favourite genre. 

Be aware it is a retro throwback title with intentionally 90s graphics if that's not your thing, but the controls, framerate, and quality of life are very much of a modern standard.

I did think the first half of the Switch's life was great, but most of my top games came from the second half; Monster Hunter Rise, Tears of the Kingdom, Mario Bros Wonder, Metroid Dread, Bayonetta 3, Dusk, Prodeus, Xenoblade 3, 13 Sentinels, Kirby and the Forgotten Land, etc. Guess it does come down to taste.

Engage is the successor to Fates especially Conquest* (but significantly easier than Conquest, which is the hardest FE in my opinion), while Three Houses is more like the successor to Echoes: Shadows of Valentia

The gameplay is different, the art style is terrible, and the story is lackluster

Map design is awesome easily top 3 in the franchise unlike Three Houses, where the maps are rather poor. Combat mechanics are refined, even more than Three Houses. It lacks a bit in RPG elements but is rich in tactical elements.

It features a larger cast and is "Ironman-friendly," meaning it lets you lose units without much penalty (in Three Houses, if you let your units die, you're in trouble). Almost all characters will join you automatically, unlike in Three Houses, where you need to grind support to recruit them

It doesn't feature the calendar system inherited from Persona. instead, it follows the Sacred Stones/Awakening structure, with story progression tied to maps and optional skirmishes if you feel like it.

In my opinion, it's an FE game for FE veterans. If Three Houses was your only game, I'm not sure if you'll like it.

Oh well, without the calander progression I doubt I'd like it as much. The tactical play while good and addicting wasn't really what made that game great. It was one of three pillars. That, the calander progression and the characters. I would hope for a Three houses sequel that expands on these ideas, namely expanded on exploration during the calander cycle, having an open world instead of just a hub town/school would blow skulls wide open.

3 Games for each year. Plenty of releases to like.

3019 was my personal favorite year...to be serious for a moment: Too many games to list. Some of my favorites since 2020 are Zelda TotK/EoW, Pikmin 4, Mario Wonder, Metroid Dread, KirbyTFL, Mario RPG Remake, Paper Mario TTYD Remake, Metroid Prime Remastered.

(The lack of Pikmin 4 and KirbyTLF is highly concerning.)

Oh yeah, I forgot Rise was a Nintendo exclusive. I suppose that was the last good Nintendo game I played even though I played it fully on ps4 and it's expansion.

Damn. Interesting point of view. There's tons of great games on Switch. You have definitely missed a ton. There's too many great games on Switch for me to even keep up. I could probably skip the entire next gen and just spend that time catching up on my Switch backlog.

I won't bother putting in a list, but you're talking about a system that will likely end up being the second most successful system ever, needless to say it has had a ton of great games come out on it in the past few years.
