When Free Realms shut down, my youngest, now 9 years old, was heartbroken. Although he didn't really do much questing, he loved the other activities in the game like kart racing and exploring the housing system. I have attempted to get him to jump into games like Wizard101 and Pirate101, whose combat systems were more complex than his liking. But he's a fan of combat in SHSO. He also plays Minecraft daily and has really adhered to the whole culture that surrounds it.
So when LEGO Minifigures Online opened its beta, I thought it would be an excellent combination of both SHSO combat and the building systems of Minecraft. I was wrong on one count but right on the other. My son loved the combat system, at least.
