It's my understanding that Fire 'n Ice is actually a very underappreciated gem and is highly addictive. And yeah, the cart ain't cheap, so this is very welcome.
I don't know anything about Psycho Dream or Doomsday Warrior. And the only thing I know about Prehistorik Man is that it's a 2D platformer. I have the game on Game Boy, but I've never played the SNES version. I'll give it a spin, see if it's any good.
EDIT: What's more important, is on that same day (2/17/2021), the AMAZING SNK vs. Capcom: Match of the Millenium will be available on Switch as well! It's gonna be a big day for retro Switch gamers!
I don't know how fast I'll find myself going to try these, but I think it's cool to see all these niche games getting new life. It's fun to see the side of the NES and SNES histories that I never really knew about.
They need to port Mario Is Missing (SNES) to this thing.
