Japan-based game developer Asobimo is working on a new mobile MMORPG going by the working title Project Eternal.
Boasting high-quality visuals, the game seems to be of very high fidelity with regards to graphical quality. If eye candy matters to you, this is something to check out. Large-scale battles against big monsters are also the selling point for this game.
To get a better idea of what the game entails, it is possible to check it out yourself by signing up for the closed beta using the link here. For everyone else, they will have to wait sometime until autumn for the game to (hopefully) come out globally.
