We are big fans of the Lego video games, and we were super excited about Marvel Avengers. Sadly, this game is very violent much more so than Marvel Super Heroes. In particular there is a battle between Hulk & Hulkbuster that is particularly gruesome. It looks like blood is spurting out of Hulk's head while Hulkbuster repeatedly punches Hulk's head into the cement. It's terrible.
The game is basically snippets of the Marvel Avengers movies which are PG-13. Unfortunately, they choose the movie scenes that earn the PG-13 rating. If your kid has to have this game, I suggest you play level 9 for them so they can skip the Hulkbuster battle. I'm finishing up the game for my 9 & 5 year olds so they can have full free play in NYC.
