That's the thing though, you can't compare the development of Dreams to other games imo. It's a game that is also capable of creating entirely new games, in any genre, any kind of perspective, in any style you can imagine and not just games but also music and movies. Expecting this to work with no problems within 24 months is how you get crap like Project Spark. As bad as I want Dreams I want them to take as much time as possible, there's literally no one else that makes the type of games they do at the quality they do. It taking a long time doesn't = they're having problems, especially when they've been so open about the games development and progress.
All the gloom and doom talk or "concern" around Dreams is unwarranted if you ask me.
