Here is the translation: "Since srpgs like Shinyaku Eien no Aselia and Yuukyuu no Euphoria are too big as projects to be funded using crowdfunding as well as other difficulties (Clephas: In other words, 'SRPGs suck development funds like an elephant does water in comparison to normal rpgs, which are somewhat simpler'), we want to first make a standard dungeon RPG while keeping the contents at a somewhat lower development cost. That is 'Mugen no Nanato to Yakusoku no Kishidan'.
Edit: As a note, the proper translation for the last game's name is 'Illusionary/Fantastical Nanato and the Promised Knights'. 'Mugen' with that kanji combination doesn't translate so well in this context, so it is best just to use the Japanese title.
