I've been playing it heaps too...
I feel exactly the same way about Dragon Ball Z Budokai Tenkaichi 2. I could play that game forever I reckon. Graphics aren't fantastic, but every time I play it I just have SO much fun. More than godfather, it feels awesome doing some of the Dragon Ball Z moves... I get sweaty and tense playing that game.
I don't believe the Wii is about having exact motions and movements to make sure that the game feels okay, if it is SORT OF what you are supposed to do, while also keeping button combinations and buttons and 'video game' elements, it really brings some new stuff to the table.
Games like this and DBZ give me faith in the 'new way of playing' that is the Wii and that it isn't just a fad... I just can't wait to feel what some of the big Nintendo games are going to be like to play!
Mortal Kombat Armaggeddon, Scarface, Godfather, DBZ they are all going in the right direction and are what is REALLY showing me what the fun of the Wii is ALLLLL about!
My feeling towards the Wii has picked up considerably in this last week.
