If you're playing completely solo without friends, here's stuff to do.

1. Unlock every block
2. Make a self reliant space station as your base (using renewable power like solar)
3. Make a space station connected to an asteroid (extra points if it's inside one)
4. Dig to the center of any planet or moon and build a base there in the center
5. Gain max reputation with Space Pirates (through grinding other faction's parts or killing spiders/wolves)
6. Build a space elevator that goes out of the atmosphere of any planet or moon (extra points if it reaches 0 gravity, even more if it connects to another planet or moon)
7. Recreate any real spaceship
8. Recreate any real space station
9. Gain max reputation with every faction other than Space Pirates or Space spiders
10. Use your imagination and make something cool, like a dragon with wings using hinges

Disclaimer: These can be done in the following sections as well, but I saved those sections for things that are multiplayer only

If you're playing on a world with friends, here's stuff to do.

1. Make an arena and fight your buddies with weaponized rovers, guns, whatever
2. Make a spaceship with a copilot seat that handles small things like hinges for landing gear
3. Do a manhunt without jetpacks
4. Make a normal house on Earth and roleplay for the funny
5. Build a large planetary base with multiple "sectors", with each "sector" controlled by one player (for example, a construction sector for refining and building, and an economy sector for shops and ATMs)

Disclaimer: Like the last section, these are also possible in the next, but I saved that section for things done in servers

If you're playing on a server, here's stuff to do.

1. Connect a Warhead to an enemy's base and blow it up (extra points the deeper into the base it is)
2. Make a faction and get half the server to join (extra points if the whole server joins)

If you're playing on a server as a faction owner, here's stuff to do.

1. Start a war with another faction (the more players on each side, the better)
2. Make an alliance with another faction (same as last time, the more the merrier)
3. Make a base on every planet and moon, with high ranking members of your faction as commanders for them
4. Take over an entire planet or moon, with multiple bases covering it

If you got here that means you're cool as heck

If you have any additions you wanna add to any section, lemme know
