I play games online right when they come out, but most Wii games sit offline as I prefer the online play of X-Box Live to Nintendo's network.
I have spent over 300$ on VC and WiiWare titles (Don't know how many games too many to count, my whole internal memory is filled up and I had to remove some games to make room for other ones)
I use the Nintendo Channel to watch that new show called Nintendo Week or what ever. I used to use many other channels like the vote channel etc...etc... but I found they took up too much space on the hard drive so I removed all the unnescessary channels!
