Dragon Quest Builders is releasing next month for the PS Vita and PS4, with a demo apparently releasing before launch. Discovered by dracula_x on NeoGaf, the demo is for the PS Vita release and its out now as of this writing on the EU PSN Storefront. It will likely release for the NA Storefront and a PS4 version of the demo should be releasing today too.
Its nice though that players can experience the game before launch and I will be covering a first impressions on the demo once it goes live on NA PSN. The file size for the demo is 226MB.
