MMORTS genre, the list of contenders is slowly but steadily expanding. Add Dragon Crusade to the list; it's an upcoming free-to-play browser title just announced by Aeria Games. The game will feature six different races, each with its own strengths and weaknesses as well as a unique racial capital. The core of the game, however, isn't meant to simply be your choice of race; it's building an actual kingdom over multiple cities.
Kingdoms are meant to add an important strategic resource to the game. Players are responsible for the defense of their cities, forcing a balance between gaining new ground and protecting what's already there. Players will also be granted a variety of different heroes, mounts, and pets, all of which have special development paths to give player forces a unique flair. There's no word yet on when the game will go into general release, but potential players can register for the upcoming closed beta on the official site.
