I love the Speed Square, but then I never really tried to get anything from it that much, I used it (and pretty much everything else in the Gold Saucer) as a way of relieving stress before heading off to the next mission. The Speed Square, Chocobo Racing Square, and everything except the Submarine game in the Wonder Square were just things I did for a bit of fun, because I loved them so much.

The only thing in the Gold Saucer that annoyed me at times was the Battle Square, and I enjoyed it too when I wasn't really trying for anything, but it did when I cared what prize I was getting, so if I cared about the Speed Square's prizes more, I'd probably share your frustration.

For those who don't know this yet; the Speed Square is easier if you press circle rappidly, rather than hold it down - that way, your lazer will never get seriously low, and this is very useful for destoying the big UFO. Also, one of the lights at the end is a target (I think on the left) just before the ride ends.
