The indie game dev community is incredibly hard to break into (you basically have to work on your game eating ramen for 18 months, and even then you're not sure you'll even succeed), but it's one of the industries with the most pleasant people I've ever met.
I'm not an indie dev, but a few friends from college are, and I get to meet a few of those guys here and there at GDC etc.- they're just delightful. Nerdy friendly guys who are incredibly smart, hard working, with an incredibly diverse set of talents (the skills needed to make a game are immense- programming, visual arts, music composing, game design, marketing- and a lot of those guys do all of it by themselves or with just 1 or 2 other people) and know to have fun.
Paradoxically, the gaming community is one of the most negative one ever (hordes of disappointed gamers will flood your blog and insult your whole family if you don't give them exactly what they want). That contrast is super weird.
