Sega of Japan has launched a new browser based game inspired by the Phantasy Star Universe series today. It's called Phantasy Star: Eternal Planets. From the screenshots I've seen, it seems to be a card based game. Perhaps something like PS Online Episode III, but probably not at the same level of depth.
You can see a few screen shots of it at
andriasang. The game itself is found at
Yahoo Japan and requires a Yahoo Japan login to play. Everything - on the Yahoo site and in the game - looks to be in Japanese, which is going to be a hindrance to most here who might be interested in it.
