Sysa,
Thanks for posting these. My C:\Program Files\EA GAMES\The Sims 2 Seasons\TSData\Res\NeighborhoodTemplate folder only has a G002 file in it. Will it still function properly if I add the G001 folder you have created? Where did you find it??
The G001 folder goes to the C:\Program Files\EA GAMES\The Sims 2 Seasons\TSData\Res\
UserData\Neighborhoods folder, with the usual instructions (delete neighborhood.package and Characters folder, copy contents of rar into their place).
On another note, I've uploaded the Maxis-only original hoods
here (and I have the others as well, if anyone needs them).
