Install Instructions Warning:DON'T put these into TS2, these neighborhood are NOT meant to play in TS2. Instead, download recreated versions of the Sims Stories neighborhoods if you intend to play these neighborhoods in TS2.
Some how managed to import Sims Life Stories neighborhoods into TS2. Some say, if you first move the neighborhoods into a Uni+NL+OFB EP game only, go into each lot and make one structural change, you can move the neighborhoods into an all EPs game. But this is still a experimental approach! You might end up with crashes if you do so.
Which is why you should download recreated neighborhoods for TS2. Four Corners and Bitville are both available for download.
