The problem with F-Zero GX's difficulty is that a good chunk of it stems from playing through four long Grand Prix races only to lose all that work because another car bumps you off the track on the final lap of the final race. I know there's a continue system, but it seems insufficient when the game moves at such a speed and the opponents are so aggressive that it seems there's just no way to defend yourself on the more precarious tracks with no walls. I think the fact that the AI is so good is definitely in the game's favor, but it literally feels like the computer is cheating by driving the race in such a way that basically all of the other drivers are conspiring against you. Some of the AI cars will drive so aggressively that they can't possibly win the race; all they care about is knocking you out. Yeah, that's unfair, and it makes the game frustrating for many of us. Game difficulty is a complex issue, so if a game reviewer is going to complain about a game being too hard (or not hard enough), he or she needs to back that up with a full explanation of why the game feels unbalanced. The reason you don't see it happen often is that doing so requires a pretty good understanding of game design, which not all reviewers have.
