The Wow factor lasted about an hour or two for me.
Followed by the feeling of "gezz..this is SOOOO right"
After which was the feeling of "Why wernt they doing this earlier?"
and
"How could I possibly go back to just button-press's when this is just so much more fluid".
And what was just Wii Tennis.
Wow factors never last long.
What the Wii gives is long-term satisfaction. Im still playing WiiSports once a day, even if its a quick session, I feel the *need* to play.
The Wii controller just melds so much with you its hard to go back to normal controllers.
Its not just the motion senseing either...merely having your hands seperated feels so much better.
