Is there anything more boring to watch than a mmorpg trailer featuring gameplay that isn't "actual (showing UI, and such)" gameplay?
Yes the trailer looks awful but at least in my opinion, so does 90% of mmorpg gameplay trailers. Especially that shows no UI and such because quite frankly, I got no bloody clue to what is going on and that just makes it boring.
In other words, The importance of this trailer isn't very much.
