Sony Computer Entertainment Japan and Asia just announced today a "Double Purchase Campaign" for Japanese gamers that will purchase the PS4 versions of both Dragon Quest Heroes and Final Fantasy Type-0 HD.

Those that will purchase both games (and register the codes included in the box, unless they have the digital version, in which cases they're registered automatically) will have to download the raffle ticket from the Japanese PSN here.

Among those that will download the ticket (everyone can access it, but you're eligible only if you have both games), Sony will raffle 100 limited edition PS4 HDD Covers themed after the two JRPGs by Square Enix, which you can see above.

On top of that, everyone who will participate (still requiring the purchase of the two games, of course) will receive a free PS4 theme, which can you see below.
