We're using Unity (Quarter Circle Games). I'm happy to give an interview and some of my lighting/PP techniques. You can view out game here: https://store.steampowered.com/app/907500/The_Peterson_Case/
This is a fan project, like the Lord Inquisitor was. GW has absolutely nothing to do with it!
The video featured what seems to be some sort of portal that is located near a mountain. The structure itself consists of a set of pillars built in a circle. In the center of it there is a strange glowing triangle floating in the air. The location has a bit of a sci-fi feel to it.
This video featured music from the LIneAge 2 MMORPG created by NCSOFT.
