After finding myself in a situation where I thought my wii was faulty I did alot of analyzing of bowling in Wii sports. Here are my results, and I'd enjoy getting a few comments on this, are you having the same experience?
There _IS_ a direction fix in bowling, there is no doubt about it. When the game thinks you are spinning in the wrong direction, the direction will be reversed for you (at no expense) :P Try this: Start a new game of bowling and move yourself just a little to the RIGHT, now try to spin it to the left. No matter if you spin to the left or the right it will always spin LEFT. This is true for both a right handed and left handed player. Another example: Let's say there's only one pin left to the LEFT. Now move yourself a little to the left and try spinning RIGHT, there's no way you can do that! HOWEVER, if there are several pins on the LEFT SIDE you can actually set yourself to the LEFT and still be able to spin both ways providing that you are spinning towards the middle left part, ie, you cannot set yourself to the far left and spin left or toward the center and spin right. How the game acts when there is one pin on either side I haven't tried but I'd assume you are free to spin either direction. What the game will never allow though no matter the number of pins left, is being far left and spin left or the other way around.
If the game doesn't KNOW what direction is "correct" it will default to the opposite direction of the hand the player is set to. Once again: start a new game of bowling with a RIGHT handed player. Don't move at all be dead center and now spin to the left, then try the right. It will always spin to the LEFT no matter what direction you try. If you were LEFT handed it would always be spinning to the RIGHT instead.
I don't know what I think about this "feature", I dislike it, that's for sure but honestly for a GOOD bowler it will probably never make a differnce. The only thing this would affect would be poor bowlers and since they are so poor they may need it anyway, right, maybe nintendo wasn't so stupid when they did this. I would have enjoyed a switch for it however as it just doesn't feel right to be "helped" by the game.
ps: my previous suspiscions of a broken wii has now been withdrawn as I simply found myself to be the cause of my inability to bowl straight, first because I wasn't very straight in my motion but second because I didn't know about this direction fix and always tried to be abit right to prevent the left so to speak but that will not work because of the fix, good to know for others!
EDIT EDIT EDIT:
In important note aswell for bowlers trying to bowl straight: MIND THE DIRECTION FIX. Since you are only able to spin in ONE direction most of the time you cannot really "try to spin a tad right to avoid spinning left", it's probably a pretty common assumption but it WILL NOT WORK because of the direction fix. You will just end up sending it the same WRONG way anyway, remeber that!
