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.
Never got to play Kolibri but Ecco was the shit for its time. I'm bummed no one ever made an updated version on more powerful systems. The 32X version was just the Genesis version with a bigger color pallette if memory serves.
Wasn't there a Dreamcast Ecco release? Not sure if it was any good.
Even though I owned a Dreamcast, I somehow missed Ecco ever being released for it. Reading up about the game, it looks like a fun time.
