Last week we reviewed Spirit of Hero, a Windows Phone-exclusive MMORPG from Vietnamese developer TeaMobi. Although a large and potentially fun game, Spirit of Hero suffers from a poor English translation and several technical issues. I must be on a janky Asian games kick, because today I?m back to review Raiden X for Windows Phone 8 and Windows 8 and RT. This one comes from a Chinese publisher called Kim Labs and indie developer HeartTour. Although Raiden X bears the name of the famous Raiden shoot-em-up series, it's not an official Raiden title. The developer borrowed the name and a few assets and made their own Raiden game without permission of Raiden owner Seibu Kaihatsu. Yet unlicensed fan games like this are actually part of a longstanding tradition in Japan and Asia. They?re called doujin games, and exist in something of a gray market in their native countries. Some doujin games are great, while others are totally amateur hour ? like Raiden X.
