Ok, it turns out the Charr, one of the races that'll be playable in GW2 will be
very steampunk. In the original GW, they were mainly tribal, nomadic, with very little technology. Alot like orcs, but instead of green-skinned humanoids, they are giant, violent cats

Anyways, looks like they've grown to be very technological, not as much as the Asura, more industrial-looking.
One of their main cities will be the Iron Citadel, which you can see in the trailer, looks like an industrial city with gears everywhere!
Here's some pictures of the Charr and their technology. The one with the bazooka isn't particularly steamy, but it's an awesome example of modern-ish technology in a more fanciful industrial setting, which is fairly steampunk to me. The picture is also awesome. And then there's the pic of the Charr with the flamethrower, which is another awesome pic of awesomeness.(sorry, if I'm overusing the word awesome, I just like the idea of 10-foot tall pyromaniac steampunk cats

) Love it's glowing goggles!
