Gamescom wrapped up well over a week ago, so why are we just seeing the Torment: Tides of Numenera Gamescom trailer now? This, I cannot answer for you. I can say, however, that it looks really good.
What I like most about the footage is that there's very little focus on combat, which is typically the central element of RPGs. In fact, it specifies that “combat is not the only option,” and while you're bound to get into a tussle or three, it's nice that it doesn't always have to be your Plan A.
For me, that really hearkens back to how I approached Planescape: Torment, which was one of the first (and still only) fantasy RPGs in which I elected not to play as a meathead with a sword. The setting was so unusual that a completely different approach seemed called for, and it really worked out. Talking, instead of murdering, my way through the game was tremendously rewarding experience.
We had a close look at Torment: Tides of Numenera earlier this year and while it was in a rough pre-release state, it was also very promising. “Every old-school Torment fan who worried that their favourite RPG might lose its sense of strange in the absence of the Planescape license can be reassured that this isn't the case,” we concluded. It's currently set to come out in early 2017.
