I stumbled upon Puzzle Fighter completely by accident back in 2009 or so. Back then, Gamestop was phasing out their GBA supply, and I'd often go to stores and ask to look through their boxes of stock. It was an insane time where you could get ALL of the big hitter games for under $10. And you could impulse buy a wide array of weirdo things that looked interesting for just a couple bucks.
So when I saw a Capcom game called Super Puzzle Fighter II Turbo for under $5, how could I pass? It sounded weird enough to be worth a try. And boy was I right. This became my go-to GBA puzzle game. And over the years I've played (I think) every single version and re-release of this one. (FYI, the title of the game is sort of a joke. There was no Puzzle Fighter I. Although there was a game released simply titled "Puzzle Fighter" in 2017... on mobile, and it was delisted in 2018. WHY the heck didn't Capcom reboot the series for Switch instead?)
At any rate, this game is pure comfort food for me. I fired it up last night and blew through the arcade mode in a single credit. Then I decided to delete all save data and go through the Street Puzzle mode, which is a series of challenges - think of it like a campaign. That mode is more challenging, and should keep me busy for a couple nights anyway.
If you don't know, this is a game about dropping gems to form bigger gems and then use explosive gems to set off big chains. It's kind of hard to explain, but super awesome. I'd also note that Crystal Crisis - a somewhat recent Switch game - is a complete and total rip-off of Puzzle Fighter except it uses indie characters instead of Capcom characters. Crystal Crisis is not as good, though. It lacks the great music, the charming sprite work and satisfying FEEL of dropping/exploding gems. It also lacks Morrigan.
