Gamestop Grievances

Even all this time after its development, the Wii is almost impossible to find in stores, unless you are either very determined or very lucky. So, when a "refurbished" Wii was made available at our local Gamestop store, we snapped it up, congratulating ourselves on saving a few dollars. My wife also picked up Spyro: The Eternal Night for said Wii, also used. This is when the trouble began.
My wife presented me with the Wii, the WiiFit and the game as an early birthday present and I eagerly popped in the game. The game began taking me through the tutorial, and everything was going fine until I was given the instruction to thrust the "nunchuck" attachment forward to whack an enemy in mid-air. I thrusted - nothing. I thrusted harder - still nothing. I threw my shoulder out of joint - ow. And still nothing. So, we took the nunchuck back to the store and replaced it with another used one. Minor inconvenience, nothing more.
We returned with the nunchuck, I restarted the tutorial and, before anything else, I tested the nunchuck. Worked like a charm. So I got through the beginning of the tutorial again, to the part where I needed to use the maneuver and thrust my nunchuck forward - nothing. I thrust, shook, tapped, jabbed and flicked the nunchuck - nothing.
I rebooted again and, through experimentation, discovered that the nunchuck thrust maneuver worked perfectly until I hit an enemy, at which point it gave up. Aha, I said to myself, it must be a software issue! So we took another trip to Gamestop and exchanged Spyro for another game, Mercury Meltdown Revolution. Avoiding the issue of the nunchuck entirely, this game uses the internal tilt sensor on the Wii to tilt a table as you guide a blob of mercury through a circuitous route, similar to the old game Marble Madness. I popped in the game with great anticipation (though somewhat less zeal than before) and started up the tutorial.
This time, the problem was more immediately evident - the table was stuck. It seemed to believe that the Wiimote was perpetually tilted down and to the right. Only if shaken VERY, VERY hard did the table do so much as twitch. Aha, I said to myself, It's a problem with the Wiimote this time! After trying Nintendo's online technical assistance (replace batteries, resynch Wiimote, reset Wiimote, hit Wiimote button-side down into the palm of your hand, etc.) we made another pilgrimage to Gamestop and returned the Wiimote, picking up another used one in its place.
With fingers crossed and a degree of consternation I started up MMR again - and the Wiimote worked. Everything finally worked, and it looks as though we will continue to have fun with MMR for quite some time.
Now, up until this point in the narrative, I can imagine what you're probably thinking. It's not Gamestop's fault, you just misdiagnosed the problem. But wait, there's more!
One of the options with the WiiFit is to run together, each person with a Wiimote in their pocket to track their running speed. My wife and I decided that it would be fun to do this together, so we used the last bit of the Fat Fund to buy another Wiimote (Used, of course - it's $5 less!). We brought it home, synched it up and ran together. The new Wiimote seemed to be responding sluggishly, since my wife quickly fell behind, for all that she pumped her legs like they had hyperactive hydraulics. We then tried using it for other purposes and discovered that neither the tilt sensor nor the light signal on the front were functioning up to spec. Oh, crud I thought to myself, not again! After trying all the available tips, it was back to gamestop *yet again* and got *another* Wiimote, this time a new one - we had seen enough of Gamestop for a while.

Moral of the story: Don't get used stuff at Gamestop. Just don't. You'll spend more on gas than you'll save getting it used.
