I used to have a 32x back in the day, but you know, Sega did what they did, and it didn't really pan out. I thought the mushroom system was cool tech, but lamented how little value it added to the Genesis. I essentially gave it away.
The library was small, and even the top tier A-list games barely even graze competency, let alone "good". Most of them play well enough in emulation (there are exceptions, of course), and even Mister has a core for it now.
Still, I unironically enjoy Cosmic Carnage; Doom on 32x was sadly rushed but the result is hilarious for so many reasons (my favorite is the end of the game dumps you into a fake DOS prompt); and I still remember being legit excited to play Mortal Kombat II on the system, and it got a lot of mileage. So it wasn't all bad.
It may not make a lot of sense to buy it again now for the nostalgia, especially with all the benefits of hindsight I have. Did it anyway.
I'm always open to potentially taking unwanted game consoles haha. But you should just look locally, you'd be surprised who wants it. And believe it or not, Facebook marketplace is fantastic for sellers and buyers alike. It's like a better craigslist and literally the only thing good about FB these days.
