i like the menu, simple, easy to navigate and and it looks nice as well...
...now, i would say this is a pretty hard request, but this is something I always though a pokemon game should have, and you are that kind of developer which is always open to doing small fan request which add up to a great game, so anyways,
i was thinking, you know how all handhelp pokemon games have always a console beside the hero's tv? So, my idea is to have that console (which could be even a PC or laptop in this case) actually be used for various purposes. So basically you would position your character in front of it, turn it on, and a variety of options would appear, such as playing a mini game, seeing the credits of the game, receiving mail from other in game characters, and as you play you would unlock more things to do in that. there was also a device you could access from the menu, the pokecyber, maybe these features could be part of that device, but still i would like somthing else to be said when you "speak" with your wii beside "It is a Wii! It is controlled by a WiiRemote!"
If you do implement this idea, i could sprite that for you (the minigame, the mail system...)
(woah, huge text up there)
