PSP edition highlighted because it's a totally different game from The Sims 2, it's just poorly named.
Truly a great game, the only game in the past 8 years that gave me a sens of mystery.
Play it ! But don't buy the original game disc as it runs poorly from it on the PSP; loading times every second, this isn't a hyperbole, the game needs to load walking animations, interaction animations ect... by physically spinning the UMD disc.
Go to https://www.pspunk.com/ for a very very very easy PSP custom firmware installation tutorial if you want to play it on the original console.
