I had to look this game up, and apparently it's still in development.
If I remember correctly, the original idea was to have Jade return, but the concept shifted to a prequel. The general consensus is that the game is botched, which is not a good sign for something that's been in development for about 20 years.
Say what you will about Duke Nukem Forever, but at least people genuinely thought all 10+ years of development were going to shine through in the final product.
Didn't the original game only have modest success to begin with? I know Prince of Persia: Sands of Time did well enough to get sequels, so maybe BG&E did well too.
Either way, I still have to play through BG&E.
