If TERA isn't a massive hit we can't blame En Masse for not trying. They're attempting to make contact with videogame niche groups of all types, most recently reaching out to the very quirky (and generally older) magazine-reading audience. Check your local bookstore's magazine rack for the July 2010 edition of PC Gamer magazine, which contains a short pre-E3 blurb about TERA! Here's a cropped, resized version if you live in a country that doesn't sell PC Gamer. This is not a full-page article, just a quarter-page preview, but it's still a good sign.

Look for more magazine articles and a ton of online previews/reviews during/after E3. En Masse has a bunch of videogame media folks lined up to test-drive TERA during the expo and you can be sure almost every single one of those guys will be impressed enough to write at least a paragraph or two about their experience. ;)
