I don't think any of those games are available in Australia, we have a limited and much overpriced range. Most games go for $60, pre-owned. They pay the orignal owner $5 then charge $60 while every other region pays $35 brand new. Also our dollar is worth MORE then the US dollar now, and we still pay these obscene amounts while retailers whinge about how "cheap" the internet is.
I wish we could get some obscure games like Dragon Quest 5 etc, so that I could nominate a "most underated game".
This is why games are region locked, so that Nintendo can continue to exploit Australia.
