A much better game than Heroes of Gaia, but a frustrating case of deja vu for badge hunters... I'm kicking myself for naively thinking that after that game, I'd never have to play it again... and now I essentially am.
This isn't an MMO, but it has many factors in common - namely grind and pay-to-play. Good MMOs do a lot to disguise that and make you think you're just playing for fun. The arbitrary energy recharge system and Kred ads on every page destroy that illusion; hard to call this "good" because of it.
