One of the most obvious examples of this is the hit indication. While some objectives and enemies will react to impact, not all of them will. This means that discovering the next course of action is trial-and-error-based on whether or not five consecutive thwacks from Ty accomplishes anything. If it does, great--you have an idea of what to do. If not, then you find the next obvious-looking object to attack. This is indicative of a larger problem with the graphics, which is that they're bad. Light sources in the game make little sense, environmental hazards don't always line up with their collision, and many things that look like they're important aren't. There are a few neat details here and there, but for the most part the graphics look equivalent to the earliest stuff seen on this generation. They are particularly bad on the Xbox version, which doesn't even offer a widescreen mode like its PS2 and GameCube counterparts.
There are two multiplayer modes for up to two players, but it's about as simple as multiplayer can get. You can have kart races against the other human opponent and six CPU players on one of six levels, or dogfight one versus one on four aerial maps. There is no choice to change any of the options--not the number of laps, death-tally, number of CPU players, or even the method by which the screen is split (it's always horizontal). So, despite having multiplayer, it's about as bare bones as it can be.
Even a younger crowd of gamers should look for something a little more complex than this.
The story is cute and might appeal to younger audiences, but it's a bit silly. It's certainly interesting that Ty is Australian, and the characters are all sensibly within that universe, but it's far too gimmicky to sustain the series for this long. Ty is overly stereotypical, which is charming initially but then begins to feel forced. While some of the voice actors' accents are fairly good, a few are noticeably subpar, which detracts from the overall presentation. Otherwise, the sound is pretty good; the music and sound effects may not be fantastic, but they work well for the game.
The Ty games have always seemed to be targeted squarely at a younger crowd, with simple gameplay and over-the-top cartoonish characters. However, even a younger crowd needs to have a more consistent and interesting gameplay experience than that which is present in Ty 3. There's no doubt that there's some charm to this game, but when it comes down to a good gameplay experience, Ty 3 is severely lacking.
