"I know we've all been burned by sandbox MMOs before. Second Life left us with nothing but a weird rash on our genital-textures and a disbelief about whether or not you just tag-teamed a (wo)man wearing a giant panda suit. But the structured nature of this awesome block-painting is surprisingly addictive, and leaves you with a sense of having created the fucking Mona Lisa out of Mega Bloks."
Tiered membership means you'll come across items and quests only available if you sign up, but even so, this game has more than enough quality free play experiences to keep you entertained.
