You Explore the galaxy, there are no classes, anyone can hold any gear but there are races and these races can hold different advantages, like one race is strong so they are better at melee, humans adapt to environment quick so they get sick, burn, or exposed to to much heat/cold but live humans have a better chance that they grow immune to what they were hit by, one race has speed and agility, one is extremely healthy, and there are some more, i am coming out with the new revised edition soon. You can do missions, buy gear, go explore, cross the galaxy, rule the galaxy(hard, but possible), or run business, the chose is yours, in the game im running you are on a mission to collect items from every planet in the Galaxy, you should join.
