According to Obsidian’s Feargus Urquhart, the developer, currently working on Alpha Protocol and Fallout: New Vegas, have another title in the works that they can’t talk about just yet.
Obsidian’s using their own engine on this one.
“We have been working on another title for the last four months that we can’t talk about yet,” he said. “It’s going really well though and the team is really excited. It’s using our own internal engine so we are really able to do things our way based upon everything we’ve learned about making RPGs in the past ten to fifteen years.
“Don’t take that as a silent slam on Unreal – it’s not. Our engine, like Unreal, is a tool and different jobs can be done better with tools that are made for them. There are things that our engine may never do as well as Unreal, but likewise there are things that our engine will do that will be better than Unreal.â€
