It's mad to me that some random bloke has become so meta 'round this parish. To the point where he's actually become a thing.
What I will say though, is that I agree with you wholeheartedly, its definitely sad to see players who've been around a while leave the game. Buuuut, at the end of the day, it does make sense doesn't it? I mean, I adored the originals and is the reason I backed this one back in the Kickstarter days, but I still come and go from it. I'll play for a few months, then get a bit bored or disinterested with it and stop playing. Come back again several months later, think to myself "ooh, that's new!" and get interested again... for a few months. Then drift off again. Wash, rinse, repeat. At no point have I felt the need to go into shouty mode on a forum, or make "open letters" or demand the CEO of the company pay attention to me.
I mean, end of the day... just a computer game, yeah? A really really good one, but still...
I'd say it's up to the individual if they want to create a thread about leaving - the way I take these is as a message to Frontier, not so much the community. It's most likely a futile exercise but when your company's official forum is swamped with "I leave" threads maybe it eventually triggers some action... though I'm probably a bit too optimistic here given who we're dealing with here.
Elite is a very weird one for me personally. I played since 2014 (the only other exposure to the series was the OG C64 version), maybe for a few months, then left since progress was so glacial and I couldn't get anywhere (and didn't really know what I was doing at the time). After Horizons released, I played it like a crazy person... I don't recall any major breaks from the game, maybe for a few weeks at a few times but I usually played almost daily for the coming years until this year. Never got bored, never burned out. Always motivated to try stuff I hadn't done before.
In 2018 I joined the forums, and got myself more involved in the online community by discussing stuff here, helping other players (or asking for help), meeting with people I'd recognise from the forums (some prolific ones even), I'd become familiar with who is who, a bit like moving to a village and getting to know the neighbourhood.
I also spent a ton of money on this game, no other game comes even remotely close when it comes to financial, time and emotional investment. So I can understand that some people can't simply walk away if they spent so much of their lives on this game.
I considered in the past weeks to do a Bazmeson myself but decided against it for various reasons (and I'm obviously still here... patch 6 combined with a CMDR wipe kept the candle burning, if only just).
I love Horizons, but I'm lukewarm about Odyssey, gameplay wise. The ring-fenced design of it is my biggest disappointment, and I don't think this will go away; performance issues and bugs just add insult to injury. I was really looking forward to it because I hoped after getting a bit bored with Horizons (done pretty much all I wanted to) it would extend the lifespan of Elite significantly for me, but it may well do the opposite instead. With other games, I'd just call it a day, but there's a fair bit more baggage (positive - the above - as well as negative - sunk cost fallacy most likely I'd say) attached to doing the same with Elite, so yeah... not just a computer game for me I'm afraid.
