ok, so for years you've been after him for a list. this year he has a list, but it is too expensive... can you afford to get him the system? He is 15, he will understand money is tight and may be willing to wait for the game.... or get the game, with the promise to put $$ aside each week until you can afford the console? If he has a job, he could contribute to move things faster...
does he know money is tight?
