Yeah it was similar, but there was more of a focus on the green crystals and the aliens.
There was also Rock Raiders, which was more focused on Mining then Mars Mission was, and it was also set in space on a different planet.
again it's was on a planet, I think it might be nice to see a focus on smaller asteroids and scavenging old ships to maybe repair or break apart for resources.
I always wish there was more of that kinda thing. Especially that the metal resources of Earth are going to run out, so this may be one of the most effective options. (If we could get past rockets)
