The PS2 is simply a great console. With such a vast catalogue of games of all styles there's something for everybody.
Now with the PS3's no longer being backwards compatible, £40 is not much to pay to play those old games you still have lying on your bedroom floor.
The only reason I give it 4 stars is because the online gaming on PS3 is something I thrive off. However some games do have online features on PS2, you just need to be near enough to your router or have a long enough ethernet cable...
