I have The Sims 2 and Sims Castaway for the PSP and i thought they were both worth buying and playing. Castaway does give it abit of a different level of play being on islands and building shelters and gathering food etc, but i think if you like The Sims then go for it!! You could probably get it cheap enough on Ebay that if you didnt like it you could just re-sell it and get your money back :0)
