The best video game I have ever played would have to be Destroyed All Humans 2.

The reason why I like this game is that it's challenging. You have different missions you have to do in a certain area of the world to move on. You have weapons that you have to collect as you go through the game. There are side missions that you can get money to buy weapon upgrades. Another thing is that there is a story line, there are little snipits that you get to watch. There is also dialogue that you get to choose what Crypto, the alien you are, says. Also while you are playing the game voices will start to say stuff that may or may not be relevant to what you are doing.

This game is rated T. for teen because there is violence and some mature content. I believe that the rating of the game is correct because we don't want little kids running around repeating what the Crypto, says.
