Developer tight lipped on its recently trademarked "Eclipse Engine" which it says is part of its "next generation of technology."
When Atari announced development had begun on Neverwinter Nights 2, they said BioWare would provide its developer, Obsidian Entertainment, with "tools" and "technology" from the first game to help create the sequel.
Today, the public has a clue what BioWare's next generation of technology is. The day after the NWN2 announcement, reports began to surface that BioWare had trademarked a new game engine with the United States Patent and Trademark Office. Indeed, on May 28, the Canadian developer registered the name "Bioware Eclipse Engine" under the computer software subsection of the goods and services trademark category.
