You could try to buy them next generation of Xbox when they will get older really. I have read it will be released in very near future. Between two current ones - I would say Nintendo for impulse purchase and if you want something for the future - Xbox one maybe.
Forex trading, in my opinion, is neither hard nor a bed of roses.
