"I was keeping up with all the PSP announcements over the week from America (Tekken and Soul Calibur haven't, for the record, been announced for Japan yet), and one particular announcement crossed my eye. Fate/Unlimited Codes Portable is getting a stateside release, only it will be in download-only form.
Here in Japan, the game is a full retail release, and thankfully so, as retail gives you a chance at stuff like this"
