FIFE, the replacement engine for Fallout that's been in the works for as long as most of us can remember (well...september 2005), has been trodding onwards steadily but slowly. From their blog:
Our policy was to be always honest to the public about problems and the truth is that there was only small steps forward in the last months. It seems that several developers have left the team without saying a word and that is really disappointing for usOn our forums, mvBarracuda stated "We intend to release a new official FIFE version in the next days".
Nevertheless I'm happy that some important key developers are still around
