I need to buy a small token gift for a 12year old boy this Christmas who I don't know very well. I know he is not sporty and his main interest is gaming. In these situations I would normally get a steam/amazon/itunes/Vue gift card but the nature of how/when this gift will be given means it needs to be something physical to open. I'm looking to spend somewhere between £10-£15. Do any wise gurus here have any exciting stocking fillers for theirs that mine might find exciting?
