Riot Games may dominate the multiplayer online battle arena (MOBA) market in the PC universe with League of Legends, but today, it has yet to enter the mobile MOBA market. A market that is very small but has big possibilities. Though League of Legends may not be ready for gaming on the go, Riot Games is ramping up its mobile development teams as shown by job openings posted online. This week, the company even acquired the domain name RiotGames.mobi. Dotmobi is the top-level domain introduced for the mobile web. In late August, Riot posted a job for a Mobile Product Manager in Santa Monica. The listing says the company is building a dynamic, fast-moving Riot Mobile team to help the company develop and create mobile solutions.
