I too own the DC. I've beaten Jet Grind Radio, which is a fun game! Shenmue is so realistic and awesome. I love the different Kung-Fu moves and the fact that you can interact with almost anything! However I was so disappointed when the sequal was cancelled for DC and is now moving to the XBOX
As for Skies Of Arcadia.....brilliant game. It's very upbeat and puts you in a good mood. The graphics are good and the battle system is innovative. I especially like the Special Abilities like Cutlass Fury and Pirate's Wrath. The Ship battles are very strategic and I LOVE strategic aspects in any game! The world map and discoveries are fun but I especially liked recruiting people for jobs on my airship, especially when the crew command came up in the battle system and I was able to call on my ship's crew for one hell of an attack....anyway, I know the DC is pretty much dead, but for the price it's going for I say buy it! And pick up these three games as well!
