Picked up AW:DoR yesterday and am impressed with it. I've played AW before and have always found it a solid game experience, though at times the cutesy graphics got old. The newer, darker, grittier feel of DoR is a welcome change to the game.
I am loving the WiFi battle mode, a game function that was a given, considering the capability of the system. Which is not to say I'm any good at it, but I still enjoy it. I'm just glad that they didn't hold your hand and limit you to playing against friends only, like PokéMon. I like the random, world wide battles.
