I love the Yakuza series. I'd buy it to eventually play it when I eventually own a ps3. I'd buy it to support the cause. I'd buy it to put it on the shelf next to the rest of my Yakuza games.
So yes, I'd buy it just to own it. You never really own digital games.
Support the decision to localize it!
I get that I guess, but I usually buy games that I plan on playing! At least you'll eventually get a ps3 to play it so that's good.
SEGA are jerks anyway, they're gonna murder Yakuza here like Konami murdered Suikoden.
