' Battle of the Immortals ' also showcases some very interesting social aspects.  Instead of just being passive, users that are on your friends list in-game have friendship level bars.  These bars fill with experience based on time spent grouped together.  As this friendship function levels, you earn unique buffs and skills to use when grouped with these characters that are unavailable otherwise.  This has its pros and cons in that players like myself who enjoy grouping, raiding and guild progression see measurable benefit to spending time together—though it certainly does not speak as much to casual gamers.  It is even possible to get married, complete with an instanced ceremony, to another player in this game after leveling your friendship bar to a certain degree; and again this grants special bonus abilities exclusive to the couple such as the capability of resurrecting each other even if not a healing class.

Basically, I am a bit smitten with 'Battle of the Immortals' right now, in case this was not already apparent.  I am a sucker for sexy graphics and out-of-the-ordinary pet detailing, and although I am aware that this game has the potential to irritate me down the road with grinding, right now I feel it has too many wonderful features to ignore.
