If you are familiar with Atlus' Shin Megami Tensei RPG series you will be excited to know that Aeria Games are bringing the MMORPG take on the series Shin Megami Tensei: Imagine to Europe and North America. You can now sign up for the beta (see below), and once launched the game will be operated on a free-to-play basis where you have the option to pay for in-game items.
Shin Megami Tensei: Imagine was released in Japan back in early 2007.
