Okay, I just typed this a second ago and it vanished so hopefully I'm not sending this twice.
The funny thing for me about the Wii is that I can't picture me and my fiancee not getting enough use out of it fo it to be worth the rumoured price. Here's all it has to do to keep us entirely happy with the purchase:
1) New Animal Crossing with the new "leave your town open online" feature.
2) 2 new Mario Parties (one for when they're just getting used to making the mini games focus on the Wiimote and 1 once they really get the hang of it).
3) New Bongo/Drum game. Be it using the Wiimote as sticks, as a base to plug in some bongos, or using the old Bongos in the GC slot, this can't fail for us.
4) At least one or two games that keep our interest even half as long as Yoshi Touch and Go.
That's it. Game. Set. Match. If anyone doubts that they need to know that there are times when me and her live as much in Animal Crossing as on earth, and that both of us have hit the Bongos until we couldn't feel our arms. Just Mario Party, Bongos, Touch and Go, and Animal Crossing have filled more gaming hours for me and her this year than I care to admit. Yep, that's all sequel stuff and I'm not a sequel fan in general. However, I'm sure that, say, Mario Party will play very differently with the Wii (it's a game that's made for it). As well, a perfected online experience in Animal Crossing is almost a big enough thing to be a new game. Think about it. If all 20-30 people on my friends list also leave their towns up when they're gone out, and animals move from those towns to mine, then on to other towns, bringing items, player made designs, and player written letters along with them and trading stuff between towns all the time, while letters arrive from people, and animals, in the other towns, you've basically got a hugh sprawling city. Add in the fact that the animals also move to people you've never met on your friends' friends lists (taking stuff you made with them) and it's almost becoming an MMORPG type environment. That might not excite you non-animal crossing fans, but to me that's a dream game.
As for wanting a sequel to the Bongo games, well, you can't lame me for being a sucker fo the Bongos can you?
