They've released one game on this engine and that's what I base my impressions on. As does everyone else, for that matter. OP wants IWD3 on this engine because "graphics are just beautiful, sound is awesome", which makes zero sense, and resident fanboys concur. I remain skeptical until proven otherwise. Certainly it's possible that the engine is good for more than simplistic casual corridor crawlers, but then why is DS3 one? Squenix forced them, no doubt.
