It's an interesting question and quite topical for me. My partner's mother is in her mid nineties and I often hear the phrase 'she would hate to think that blah blah blah after she's gone'.
My answer to that is always the same, she'll be gone and she won't give a flying fig about blah blah blah.
I'm clearly out on my own here because I don't care about my legacy or how I'm remembered because I'll be a pile of dust. Does that make me a bad person? I really don't know.
This may be a bit lame or whatever, but I hope those in the Sonic community remember me for the guy who liked to modify the often forgotten 8-bit games and remember when I posted guides to help add new features to Sonic 2 on the Master System. I would also want those to remember that I always did things my own way and never listened to those who wanted to tell me how I should live my life.
I don’t think I necessarily want to be remembered or have a legacy? I’d like to go out having contributed something that made the world just a tiny bit of nicer place to be.
