I only see the mustang and aurora 'starter packages'. If I get, say, a 75$ ship, does it come with the game as well? What's a good starter ship for someone who likes to kill NPCs and maybe mine? You can mine right?
Click "view all" next to where it says "Game Packages." Make sure to scroll down past the super expensive ones.
Mining is a thing, but the dedicated mining ships haven't been finalized yet, so I don't think they're for sale. As rivethead mentions below, it's not something you can do right now.
Keep in mind this game is still in early Alpha as far as development goes. When you have a package, you can go to the hangar and view your ships. You can take the elevator from your hangar to the ArcCorp Area 18 area and explore around (will be updated with NPCs soon). You can also play an in fiction "game" called Arena Commander by Original Systems (a nod to Wing Commander by Origin Systems that put Chris Roberts on the map). Arena Commander is how you can fly your ships at the moment, but in the game it is itself a video game so the consequences don't matter.
If the early Alpha bit bothers you, I would wait until the actual game comes out. Also, since the game isn't complete and is in development, I would suggest not parting with any money you would be upset about if nothing else ever came from it.
Soon there will be Star Marine alongside Arena Commander, which is a first person shooter section. These are just test modules that will eventually be combined into the final game as they finish building the infrastructure for the Persistent Universe.
You need to make sure you're looking at pledge packages and not just individual ships. Packages come with both games (Star Citizen and Squadron 42).
You do get the first of the Squadron 42 trilogy. Only original backers get all three included, I think. More recent backers have to pay for the second two chapters. Each chapter is pretty long (30+ missions I think), so each chapter might as well be its own game. CR said each in the trilogy should be 20+ hours.
As for your buying options, here's the deal. You need a "game package" of some sort to play the game. You can buy additional ships later, but you can't do anything with them without the game package. It makes sense to start with a game package that has a ship you want. Or you can buy the Aurora package and work you way up in game.
But know this.....when Star Citizen goes live, it will be multiplayer. We've heard that the ratio could be as diluted as 1 human to every 10 NPCs. But you will never be able to completely avoid humans or play offline. So if you have dreams of only killing NPCs....you might consider carefully. SQ42, however, is the linear single player campaign.
There will be a slider that lets you set how many humans you encounter. CR did say that even with it set to as many humans as possible, there will still be mostly NPCs that you come across because there will be so many.
One thing to note though, CIG has stated that at some point after release people will be able to host their own servers. So if someone chooses to they could run their own server and only grant themselves access.
While true, he has elaborated on that in 10ftC. The home server option won't be as alive as the online version. Way too much overhead to let a single home machine handle. They're simulating a single live persistent universe in the cloud with hundreds of physical machines, and not just because of the number of players. Things are happening in places you are not to keep the universe alive. When they cram it down to the home server version, you're going to lose a lot of the dynamics of the universe.
