The Simpsons Game PS3 Visiting The Simpsons Home Part 2 

The part of being able to climb the Treehouse makes it just tremenD'ohs and makes it The Best Simpson Game That Could Have Existed.

Note: In the PS2, Wii and PSP versions this is one of the only parts of the hub world that are accessible the others being the backyard and The Game Engine.

it be nice if you could tour the house in the simpsons hit and run 2003 instead of just the livingroom and bart's room

It's a totally different game compared to the ps2 version, still miss my ps2

Their house is very nice.
