Comic fans know what it's like when a favorite author leaves a book. Todd MacFarlane left The Amazing Spider-Man. Frank Miller left Daredevil. John Byrne and Chris Claremont left the X-Men. The adventures continued and were serviceable, maybe even good, but were never as great as they were before. Marvel: Ultimate Alliance 2 follows that pattern. Developer Raven Software has headed up the series since it started as X-Men Legends and their intimate knowledge of Marvel Comics has made the series a fanboy favorite. Their expertise and attention to detail can be seen in titles like X-Men Origins: Wolverine, released earlier this year. That left Marvel: Ultimate Alliance 2 in the hands of Vicarious Visions. They also had worked on the series but the absence of Raven will be greatly felt by comic aficionados.
