IMO, not really worth it. Lacks features, no Live support, lots of grinding if you want to get everything, lame graphics, and way outdated card sets (well, at least compared to today's card sets).
I'm at 99% completion list and once I find the time I'll finally get everything in the game and probably stop playing for good. --- Part man. Part demon. Pure vengeance. The body ages, but the mind is immortal.
