I saw this at walmart last night and picked it up thinking it was a new special addon package but it turns not its not at all compatible with current sims2 installs and keeps asking to "insert sims2 disk #1" over and over.While the package does mention Sims2 is part of the package, no where does it say that its not compatible with current Sims2 installs and it does not have any options to just install the holiday stuff without loading in the whole game again.You can get just the holiday addons on the Sims2 website for $14.95. Don't waste your money if you already own the game.
