Sonic Unleashed

It is pretty clear on the cover that this isnt your average chilli dog eating furry friend.
Sonic unleashed is a game about sonic the hedgehog being the normal speedy hetgehog he is but when the sun goes down becomes a werehog this is when the game get's a little more violent that the usual speeding around collecting shiny rings.The 7+ on the cover suggests it isnt too violent for a child to play some people may disagree and will choose to buy more for teenagers and young adults.

Minecraft

Resident Evil 6

The sixth installment of the resident evil franchise.

This game is aimed at 17+ year olds but most teenagers play it it is a game created by capcom about a zombie outbreak with an unknown source and you spend your time in the game taking the heads off of zombies or trying to find a cure for the infected.
This game contains some frightening scene's and is not suitable to children.

You can tell by the Official cover that this isnt a childs game it has a very sinister feel to it.

You wouldnt see a number six look like this in a childs game, this shows that it is all about shooting or knifing zombies flesh untill nothing but blood remains.
