Firstly, welcome to New Eden. You’ve done the right thing by asking here - though you’ll get a range of opinions and rants on various subjects, hopefully you’ll get a few diamonds among the rough.
Speaking of which, @Mike_Azariah is being modest: if you see him in local in one of the beginner’s system you can absolutely trust what he says. The Magic School Bus is genuinely one of the most wonderful things in Eve.
The Scanning Part, and the Hacking mini-game is all part of the wider Exploration of New Eden, the cluster of star that Eve is based in. By scanning you will find a range of sites, from combat sites (grab a ship and go kill things), to data and relic sites to hack (the “mini game”), to wormholes to Anokis and the delights of the systems there and the entities (and other players) that live within. The Eve University article on Exploration is a good starting point. Eve University is another player run miracle of Eve life.
You don’t need a fancy ship for exploration, just grab a T1 frigate, something like the Magnate or the relevant faction exploration ship and you’ll be fine. Yes, you’ll lose ships, you will be hunted, and some of the hacks will be hard. But you will hit a good payout every now and then, and the adrenaline of being the rabbit that escapes the fox, and takes the carrot home as well is a real buzz.
Exploration is a good way to learn how to fly and live in New Eden as well as being a good source of income. It’s better than mining. Mining has it’s place and purpose - I use it as gentle relaxation rather than a source of income!
The Blood Stained Stars, the Sisters of Eve Epic Arc is a good story and nice introduction to the factions and lore of New Eden, and you’ll visit and see many places on that trip. It is doable for a new player, though the last couple of missions can be a challenge. If they are causing a problem, reach out here - or in the system local - to see if someone will help. If I’m around, give me a shout and I’ll toddle over from Amarr and help.
Hypernet offers are like most casinos. You may get lucky, but normally the house wins and you go home with empty pockets (and a gorgeous ex-ballerina on your arm. That’s another story altogether!)
The options in Eve are almost limitless, much like life in the Real World. And like the Real World the win is finding something you enjoy doing then working out how to make it pay for the life you want to live. More than anything else though, Eve is a social game - it’s better played with other people rather than just on your own.
An offer I make to any new player:
Feel free to reach out to me in game if you’ve any questions or need a hand with anything.
