The moves. I've played and enjoyed other shooters, but never for very long. The groundpounders have added layer after layer of meta over the years, flags and control points and teams and bombs and powers and shops, just to build some strategic depth onto a game which is fundamentally limited. Descent remains deep at its simplest, such that interesting innovations in its gameplay look more like Ugh than like Counterstrike.
In Descent alone, as far as I know, does the master stand like the kung fu master in the movies, like the legendary ninja, untouchable, immovable, sometimes undetectable, seeming to defeat you with skill that seems supernatural in nature. Why does even a skilled player lose a fusion fight to one who has mastered the genre? How does Jediluke kill you when you never SEE him?
The attraction to me is mastery that borders on the mystical. There are amazing performances in esports of all types, but I think the skill in Descent is just... satisfying. It's inspiring and stunning to see, and satisfying to achieve at many levels. To be able to sit in the same space as you sat a decade ago, bearing weapons that haven't changed, facing the same range of adversaries as ever, and to HAVE felt frightened and vulnerable, and to NOW feel confidently invincible, when all thay changed was you... well.
Not acquired levels. Not dominance after 20 minutes of gathering and building better than you used to. Not a few special skills that you practiced to death and now you have this one unbeatable move. Just what's in your mind and hands, against all the creativity of the world. There's something very immediate, very innate, very interesting happening here, and I love it.
Secondarily, for me, it's the culture. The legacy of Sirian and Karash and Glock21 - share the knowledge, make the game great, show courage, respect improvement, cultivate skill, treasure true awesomeness and spurn mere statistics. The legacy of Kali and IDL and the peer-to-peer nature of the game itself - decentralized, build what you want to see, solve our own problems, respect what we think is worthy. Pilots in general are independent, self-reliant people, and Descent pilots have this personal characteristic in spades. And now the legacy of DCL - respect guts, fly with honor, become great together, train hard together, and see how deep this crazy art goes. I don't think we've mastered it yet, but it sure has been a privilege trying with you all.
There's a lot of other stuff I love, too. I love the struggle. I love the challenges. I love the pressure and the indomitable opponents. I love the thrill of do or die at the start of a match. I love the crazy wins that you train for for a year and finally GET. I love the exhausting workout of the great games. The fun and the adrenaline and the camaraderie. The awesome people I've met and the remarkable friendships.
Some of what keeps me coming back right now is the sense of an amazing opportunity, and the knowledge that nothing lasts. When I left the Descent world around 2002, I thought I'd been a part of something very special, something I'd never again see in my lifetime. And then lightning struck twice and here we are. And what a second chance! I have felt for a while that THIS is the golden age of the game, and even if the community is smaller, some of the coolest stuff that has ever happened is happening these days, and I don't want to miss out! I know epic pilots retire, and I want to play them as much as I can before they do.
Truth might be, though, that I'd love it if it weren't for any of that. I found that all out after I'd been in it for years, and I was already hooked. First time I spawned, in single player, on trainee, 13 years old... I flew in a circle. Flew back around the other way. Fell in love hard and I can't say that feeling has ever diminished. I might've gotten bored if it hadn't been deep enough to spend a good chunk of a lifetime studying, but I think my attitude has always been something close to, I'm a musician and this is my instrument. I'm an artist and this is my medium. I fly because I HAVE to fly. Another 6DoF could conceivably surpass it, though none I've seen have, but I think I will always feel a deep need to fly and to get better.
