Most of Ds1's (Yr 6) friends have at least one of the games. All the talk in the playground is Halo, all the games revolve around the game. Ds1 isn't particularly interested - he prefers role playing computer games - but is feeling increasingly isolated. One boy has started teasing him for not having the game or knowing much about it.
From the limited research I've done, I can see that it's a 16+, which puts me off from the start. DS says it's a shooting game, with some blood and swearing. Is it common for 10 year olds to be playing it?
