InfiniteSims caught wind of the ESRB raiting for MySims SkyHeroes listed for the DS platform. It’ll also be released for the Wii, but at this time the rating has only been released for the DS version. It does give us insight on how the game will play out:
This is an action-adventure game in which players select a “cartoony” airplane to complete a variety of missions: racing, target shooting, aerial combat, etc. In some missions, players use “goo guns,” stylized rockets, and blasters to defeat enemy aircraft. Bright colors and star effects indicate successful hits; planes disappear in a puff of smoke when shot down.
Not my type of game by the sounds of it, but I’ll need more details before I can judge it.
