I've tested out all three games that arrived today, and Yoshi's Island really is the cutest thing ever! The graphics are so cute, the noises are so cute, and, in the words of @Abcmsaj - its got Yoshi in it for fucks sakes! :)
Tony Hawk's is pretty fun too, but I'm going to have to get used to the controls on it methinks. Dragonball Adventure is nothing too strenuous, just general kiling fun :)
So now I'm OH SO eagerly awaiting the Pokemon games and hoping the Hong Kong postal service gets a wiggle on.
