The Neo-Geo era can be considered a golden age for those that loved Japanese games and for SNK, and today we got a bit of a blast from the past from its successor SNK Playmore, as five interesting trademark filing have been published by the Japanese Patent and Trademark office.

The trademarks are for "Ninja Master's" (and its Japanese lettering "ニンジャマスターズ"), the Japanese lettering of "Ninja Commando," and "Ninja Combat" (including its Japanese lettering ニンジャコンバット).

All three games were developed by the now defunct ADK Corporation (or Alpha Denshi, as it was formerly known), which is better known for the World Heroes series. Ninja Master's was a the last fighting game released by the company on Neo-Geo, Ninja Commando was a vertical scroller run and gun game, while Ninja Combat was a side scrolling action title.

SNK has been on a spree in re-trademarking ancient titles from the Neo-Geo era, but for now we still don't know if any of them will see a modern re-release.

Considering that the Neo-Geo is still one of my favorite consoles (especially in its CD-equipped incarnation), I really hope to see some of its most glorious games resurrected.
