So it's inappropriate to compare it to one Stuff Pack.
Okay, let me put it this way - Does this hold up to a Game Pack? ANY Game Pack?
Pick a Game Pack at random. Vampires. Dine Out. Jungle Adventure. Three radically different packs. Dream Home Decorator doesn't stand up to their content. Its gameplay is based around two things - the Build Mode and the new Likes and Dislikes system, which is BASE GAME - Sims seem to base their appreciaton on whether they Like the items in the room, or Dislike them.
To be worthwhile, Dream Home Decorator really needed a new world.
