Like I said yesterday, the in-game trailer BioWare showed off at Gamescom was decent. It was't really gameplay, instead just in-game cutscenes. I don't blame them for that though, traditional MMO gameplay cannot compare to what we saw with Star Wars Battlefront. Instead, what really caught my eye yesterday was screenshots posted by Massively Overpowered.
They were much more interesting to me than the trailer. Some great scenes were shown off. Go check it out here: http://massivelyop.com/2015/08/05/gamescom-2015-swtors-knights-of-the-fallen-empire-gallery/
I've included two of my favorites...
Darth Marr apparently plays a big part in the story.
I really like the look of the Zakuul Knights.
