A bit of advice for both of you: love and respect your parents while you have them. One day they're gone and it all happened too fast and you think of questions you'd like to ask them, but they're gone and there'll be no answers for you.
Furthermore, you see your own ultimate fate in their demise.

As the epitaph says - "As you are, once was I. As I am, you will become."

I buy lots of good games, to play them all I would have to quit my job I think. But then I wouldn't be able to buy games anymore, that's a dilemma.

My purpose in life is to bring happiness to my children & prepare them for adulthood. That's all I've got and all I need.

I'll just post someone who said it better then I could.

"Isn’t a person just a collection of their mistakes, and also their, kind of, undoing of their mistakes? I mean, what else are you? You know, you’re always…you’re always just the reaction to the bad parts of yourself, I think. And I think that’s what is kind of like, a driving motivation behind any human being that’s…who wants to continue to grow and live life. ‘Cause they’re looking at their flaws and trying to, go beyond it. And I think that a person, you know, essentially dies when they think that they found themselves, ya know? Unless you want to admit that you, yourself, are not an individual, and are just part of a whole…movement of ideas, and thought, and culture, and humanity and, furthermore, the universe, and everything -- unless you really feel like that, and you’re walking through walls, you know, you are always trying to find yourself. And it’s usually a person who believes that they’ve found “the answer” -- found “the end” -- that there actually is a psychological end. And then what’s the point of, you know, doing anything after that?" - Eyedea (R.I.P.)

Back when I was 20+ I have 3 big questions. Who am I? What is my purpose in life? How can I achieve that purpose.

Surprisingly I found the answer to 2nd question last, after reading Dalai Lama's book titled Art of Happiness. Then was when I realize what I really want in life is to be happy. And there are good ways and bad ways to get happiness.

Aside from family, I pick gaming as one of my source of happiness. Not only it's fun to play games, it's relaxing and in a way creative. I always like creativity and hate dull job. That's why as a hobby, if I don't play games, I would tinker around with a game engine and try to male a game of my dream. Still far from done, but so far I'm enjoying it

More about my purpose in life later (I'm just out of bed and not awake enough yet to write much), but not wanting to abandon my parents is a reason to stay alive for me. I like your subtitle 'preferably dead', I'm very tired of life as well, but there's several reasons I don't have the courage to step out of it, one of it being not wanting to grief my parents and not wanting to abandon my family, friends, colleagues and the people whom I work for. Plus there's lots of games I want to finish!

A message to you from all of us.

Yes, buying games that I need 10 lifetimes to finish.

I don't really believe in the concept of a purpose or meaning of life.
If anything then it's to reproduce or be happy, the first from a purely biological viewpoint (as in that is the point in life existing, to continue existing) and the second from a psychological one (what else can you do other than strive to be happy).

I don't think anyone is destined to do or achieve certain things, I think you need to find happiness in your life as it is, or make the easy changes that will make you happy rather than waiting for some epiphany that will likely never come.

Tl;dr: Don't worry, be happy.

Definitely, I'm a waste of space.

My lifes meaning is to produce shit to soil the lands and to leave a body that will be a feast to our worm overlords.

42 and still no purpoise

43. I like to have higher standards and aim higher than others, so mere 42 just didn't really cut it for me, when it comes to the meaning of life.

And keep buying new games in those 10 lifetimes.
