For those who don't have a Super NES Classic, Star Fox 2 is excellent! I'm not kidding when I say that, in so many ways, it's the most genuinely creative entry in the Star Fox franchise. I was shocked that Nintendo finally released an official version for the SNES Classic, but now you won't have to have one of those fairly rare machines to play it.
Journey of Silius I don't remember, but I just looked it up after reading the OP and it actually looks great! Inspired by The Terminator? Count me in, I loved the original Terminator movies and wanna see what this is like!
Crystalis I remember liking on the NES as well.
