Well, what I meant by "far easier" is that it's easier for those in NTSC countries to play NTSC games, whether American or Japanese, than to get PAL games working on our systems and TVs. Like Parodius Duh! said, you'd need a specific kind of converter to play PAL games on an NTSC system or vice versa, and even then I hear that stuff is often very glitchy. I have several games that came out in Europe but not the US that I still bought in Japanese just because I'd rather deal with Japanese text than the headache of PAL games.

Although if you're in Australia, then I suppose it would be easier to stick with PAL, unless all the stuff you own is already NTSC.
