... You do realise Iizuka was the director of both Adventure games, right? Yuji Naka was only a programmer or producer when it comes to Sonic.

How were they poorly done? They had quite a lot of depth to them and they had some really fun moments to them. The essence and key points of each level were captured perfectly. They even managed to add some references to other Sonic levels in the design.

Plus, why would Generations reference Archie or Sonic X? The game was celebrating the game character.

I would say that Forces failed to deliver what it promised, for the reasons I gave above. Generations, on the other hand, was clearly presented as a nostalgia trip, which it did deliver on. While I would've liked more variety in the levels, I think I should point out that those levels were picked by Sonic fans in a poll, so I can't argue with their level choices here.
