When your friends pop over for a quick match on Fifa or a fight on Tekken and you can't play them head on head. But in turns. This can get boring so another controller is highly recommended. But also bear in mind if you want more than 3 you will have to purchase a PS2 Multi-Tap. For around £30, on top of the £20 for each additional controller.

This is very essential if you have more than one friend. (Which most of us do!) It allows you to stick in 4 controllers,
Why Sony built the PS2 with two ports is that they say 75% of games only have a 1 or 2 player option. Then why do all other consoles come with 4 as standard? Is the question you should ask them.

At around £30 it is a bit pricey but definitely worth it. As it also comes with 4 more memory card slots. A cunning way of getting you to buy more memory cards.

It looks quite stylish and is designed and built well.
