MySims Party - IGN Preview
"EA demonstrated a handful of minis from both the Wii and DS titles to us. In a snowboarding challenge, players must twist the WIi remote classically and then press in different directions on the D-Pad to cue flips and spins. For instance, down, up, left, left right might trigger a mid-air stunt from their character, resulting in points. Simple. In another mini, players must blast skulled ghosts in a haunted house using the Wii remote's infrared pointer. In one more, they must push tiled blocks around an environment in order to eliminate gaps in walkways. From what we could tell, the minis are well-designed."
