That DAOC site reminds me of stratics for some reason, and uo.com does not look far off from it actually.
Minus the background they have the same basic layout.
If they're using any kind of content management system, the 3-column layout is standard. It takes a bit of hacking at most CMS templates to come up with anything other than a 3-column layout (as that's usually the default), and it appears that they don't want to spend time recreating the wheel.
It's hard to do this kind of web site any other way and still have it usable and navigable.
I don't fault uo.com for the layout, but their sense of spacing is bizarre. At 1600x1024 (my current resolution), the scroller banner at the top takes up at least 1/3 of the top of the page. I can only imagine how huge it looks on lower rez settings. It takes up almost the entire length of the left-hand navigation, and that just looks weird.
Things are out of proportion. That's what bugs me about it. I generally like the overall look and graphics.
I wish they'd stick to either warm or cool in the color choices though. The outside content is all black/silver while the inside is all reds/browns/beiges. The contrast is distracting.
