In one of our Japanese trademark hunts we found Sega filed trademarks for Phantasy Star: Eternal Planets and Phantasy Star: Eternal Hunters. Both were registered for use with video games. The title makes it sounds like these are going to be companion games like Pokemon: (insert color) / (insert contrasting color), but probably without Rappys to catch.
Ever since Sega released Phantasy Star Online the series evolved from long dungeons with sci-fi stories to item hunts inside long dungeons. Curious to see how a Monster Hunter game would work if its split between two titles.
