Capcom first began DuckTales Remastered talks with Disney back in February 2010
You really have to applaud Capcom for its work on DuckTales Remastered. It wasn’t easy hammering out all of the different aspects and kinks of the renewed collaboration with Disney.
Since two companies were involved, it took awhile before development could proceed. Capcom’s Christian Svensson wrote on the Capcom-Unity boards that over two years were needed just to complete the deal. Svensson first began conversations with Disney in February 2010.
Svensson’s comments in full:
It took more than two years (on and off) to do the deal even before any development started. The first conversations I had with folks at Disney about this were had at Dice in 2010 (Feb 2010).
Initial proposals for greenlight started preparation in mid-late 2011 (when it looked like we would be able to reach a deal with Disney). Active development started a bit later after greenlight was achieved.
In short, it was a lengthy process.
