| Famicom Tsushin's cross review of 3 August 1990 listed Jūōki (Asmik, cartridge, ¥5,900, 20 July) as the side-scrolling fighting action game that, after the arcade, the Mega Drive, and the PC Engine, comes to the Famicom, in which taking an item turns the hero into a beast and powers him up. Its four reviewers, unnamed on the page, gave 6, 6, 6, and 3. The first, blaming mainly the hardware, recalled that the game's selling point had been the size of its characters, but found changing into a beast felt good. The second advised taking it as a different game from the arcade one, with smaller characters and a different flavor, though not a dull one. The third found it comparatively easy next to the very hard arcade and PC Engine versions, so powering up and transforming come easily, but regretted how plain the characters had become. The fourth, giving 3, said the characters are small and there are no transformation scenes at all, that it is better taken as something wholly different from the original, and that collectors might do well to buy it now. | image 17, cross review, heading, read on the page imageimage 17, cross review, read on the page imageimage 17, cross review, first reviewer (6), read on the page imageimage 17, cross review, first reviewer (6), read on the page imageimage 17, cross review, second reviewer (6), read on the page imageimage 17, cross review, second reviewer (6), read on the page imageimage 17, cross review, second reviewer (6), read on the page imageimage 17, cross review, third reviewer (6), read on the page imageimage 17, cross review, third reviewer (6), read on the page imageimage 17, cross review, fourth reviewer (3), read on the page imageimage 17, cross review, fourth reviewer (3), read on the page imageimage 17, cross review, third reviewer (6), read on the page imageimage 17, cross review, fourth reviewer (3), read on the page image | Magazine |
