This game has been a long, LONG time coming, but the wait was more than worth it. It's beautiful, cinematic, emotional. It's packed with enough gameplay features to let each player create their own style of play, and enough content and hidden secrets to keep you coming back again and again. It is very much the conclusion to a long and complicated series, and it's decidedly unashamed of this. The developers, however, have tried to give new and existing players as many opportunities to catch up as they can (including cinematic recaps of previous games) so that everyone can enjoy it. It's a fantastic and fun game and if you're interested at all, you should definitely give it a try.
Also Donald Duck is in it.
