Bethesda working on mature Wii game

"We are going to make an announcement on a really big Wii game this year, we've got a couple of other things in the pipeline, and it's a format we're really looking at with the right approach," revealed Sean Brennan, managing director for Bethesda in Europe, in an interview with GI.biz.

"I've got consoles at home but I wouldn't sit and play an 18-rated game with my family on the Wii," he said. "Is there space in the Wii market for that? I think there is, but again, it's all about finding out how big that is. Is it 5 per cent? If it's five per cent of the market and you can own that space it's worth doing because you can achieve volume. If you can't own it at five per cent, it's not worth doing, quite frankly," he added.
