Hopefully the WiFi playing will be good compared to PH.
I hate the WiFi because everytime I beat someone they always quit. I only have 4 mor "Big Plays" left to do. Also it isn't really fun because it is nothing like the main game.
Also by the demo at E3 it shows me that their will be something like the Temple of the Ocean King. That is the one of the reasons that I have only played through Phantom Hourglass twice. I also hope that the dungeons are more challenging. I just played through the ame again and got stuck 1 time for about 20 minutes.
Last but not least I hope that it takes your drawings and stuff better. Sometimes you can draw something tat looks nothing like what you are suppose to (some of the drawings on the slate) and others have to draw it excactly perfect or it doesn't count it (Triforce on red door)
