One of the first entries in your 2017 calendar should be the release date of a 30th Anniversary entry in the Double Dragon series. Arc System Works acquired the rights to the series last year, and just announced that Double Dragon IV will be released January 30th on the PS4 and Steam platforms. Despite being the first new update since 2012's Double Dragon Neon release and first update of any kind since Double Dragon Trilogy, its trailer flashes the classic side-scrolling beat 'em up action this series has been known for since it started as a coin-op in 1987.
According to a press release, three developers from the original game are helping to create it. The original planner, designer and composer from the arcade game are involved, which should help keep the classic feel going. The Japanese price of the game is listed as 800 yen ($6.84 US), so it shouldn't be too hard on the pockets once it's released.
