"Meaning" is a human concept, and only humans can fill its definition. It's also an individual concept, so everyone has the right to write its own definition. So indeed, as long as you have any desire(s), you can walk a path towards them. Any desire is fine if it's fine to you.

There's one commonality though: we kinda have to align with other humans. Maybe you would be able to be happy meditating alone... but if there are others around you who find what you do weird and criticize you, meditating alone itself becomes harder as you will have to additionally be able to remain unaffected by the criticism you receive. In the other side of the spectrum, if what you do is enjoyed by many other people, you will more easily feel reassured that it's a good investment and that it makes sense to do it. Plus you will be more likely to connect with other people, which is like, the main desire for most people: no better way to feel that your life is meaningful than having others tell you that you mean a lot to them. And we kinda keep rolling in that loop.

So those guys have found each other and Spyro will have enough depth in some aspect that they can keep walking around it meaningfully (to them). It's all cool.

As you also hint, putting some effort to make others suffer less is also an interesting idea: suffering is kinda at the opposite side of happiness and meaningfulness in life, so reducing that is also another way to increase positively the meaningfulness score.

It's rather bizarre that we are so dependent on others to make a positive evaluation of our own meaningfulness. Like, it doesn't even compile in most languages.

But maybe god is ok with circular dependencies. Let's ask in the next code review.
