I’m not sure how you define “worth” it. I had a load of fun once I felt like I had control over how to play and what to do with my time there. I even had fun when I was losing/dying.

I quit because real life has to take priority for a while, not for anything negative about the game.

I played Eve for a few years and had plenty of fun without a corp, although I think it steepened the learning curve because there were too many competing interests.

I landed on a number of fun activities that I enjoyed and felt an adrenaline rush while doing solo, like stealing loot from pvpers and, especially, gate campers, disguising myself in a Venture and killing other miners, killing MTUs, and hauling through dangerous places (especially Pochven).

Overall, I think the game became more fun for me solo when I started putting myself into danger and hanging out around pvpers. I had to get accustomed to dying in cheap, replaceable frigates to get a sense of what was safe to fly and not get angry and ragequit the game because of some loss.

I think corporations alleviate a lot of that by having generous buyback programs and, often, free ships for members. Definitely still possible to forego all of that if you’re so introverted you don’t even want to join some corp’s comms.
