It's definitely fun solving a growing problem for developers - games aren't disconnected and audiences are massive, "I want high scores in my game" is not as simple as hacking together some php/mysql on your $8 hosting account when a popular game reaches 10s of millions of people.

I think the biggest difference ultimately is HN doesn't hold any marketing value for me or other gaming startups so none of us are making a play for it. The analytics side of my platform dwarfs many of the ones we talk about here - but the others are relevant for anyone with a registration form, so they write / submit more stuff.
