Another first, created a Japanese eshop account for an import download.
Was shockingly easy.
As for what I bought, well I found out the Japanese version of the Mega Man X Collections have content that the US download does not, due to licensing issues (namely, any game with an FMV intro or ending originally used a Jpop song. These are on the Japanese release but the US release will always use the US replacement music... even if you specifically tell it to play the Japanese version). To be honest if I had known this I would've bought the Japanese releases from the get-go instead of buying essentially the same game twice, but oh well.
