Good and Bad at once, and Genericon

So Kathy's screen (17" Powerbook) started to glitch out regularly. The computer's had a host of problems through the past year or so, including Epic Fail of the DVD drive (not only doesn't the drive work, the computer denies it has one). My own computer's drive has started to act up too (still shows on the system, won't accept any discs for burning, etc.) and it has some other smaller problems.

At Apple, the cost to fix Kathy's was $700-$800. Mine, $500-$600.

So I bit the bullet and bought new machines.

The latter is the good news, of course. Now I have a brand new MacBook 13" -- larger screen than my old Powerbook 12" and VASTLY more powerful, and Kathy has the 15" MacBook Pro, which is considerably more powerful than my new one (and prettier, too). They also feature the magnetic attachment power cords, which eliminates the single greatest point of failure in our prior computers.

Genericon is this weekend; for the first time, I think I'm going to have a minimal presence there. Too many things have happened over the last several weeks. I'll be there on Saturday and that's it, unless they've scheduled me for a panel on any other day. Saturday is the Cosplay, which I will MC.

Help from the Computer/Console gamers out there....

Question 1 is specific to NWN2 for Mac, which I got really cheap when I got my new machine.
Question 2 is more general, and about the Wii.

1) I started NWN2 on my brand spanking new MacBook, got a character, started playing. The machine freezes/crashes when I go from the starting room to outdoors; it says that it's loading the area, claims it's done so successfully, then stops, with the blue progress bar halted about 1/5 of the way. I have to hard-shutdown to get out; the cursor's gone and no keypresses have any effect. What's going on, and can I fix it?

Edit: The bad news is that my current machine apparently can't do it due to bad graphics card selection on Apple's part when they did this model Mac. the GOOD news is that the same model is coming out WITH a better, and presumably compatible, graphics card and doing so within a week, so I can TRADE IT IN and get one that works.

2) I've heard that a number of games for the Wii can, if played enthusiastically, be exercise as well as fun. My interest would be in RPGs or possibly action games along this line. Doing exercises just for exercises wouldn't do it for me. Any input as to whether there are such games?

Edit: apparently not yet due to the Wii controllers not being QUITE good enough and thus no one coding for that sort of thing. But perhaps in the future.
