I've been part of an administration before, and one thing I learned is how to spot a party line -- a pre-defined list of things you're supposed to say no matter what. I noticed in videos of the Creator's Conference that when anyone asked one of the developers a question, they always steered the answers to specific positives about the game.
I can assure you that this is not an accident.
The people working on the game have most likely been ordered to keep certain things quiet and keep harping on others, such as the "innovative" new town design or the "amazing" traits system.
Of course, some things haven't been decided yet, so they can't give straightforward answers. Others are supposed to be surprises, so they shouldn't give straight answers.
But the truth is, when everyone is saying the exact same thing, repeating themselves, and sidestepping direct questions, it is a conspiracy.
This particular conspiracy to limit information and really push the major differences between Sims 2 and 3 is not surprising, though it is annoying for those of us who keep up to date with all the new articles about the game -- when the last seven have read exactly the same, you can almost quote the new article's phrasing before you click the link. They all cover the town design, create-a-style, fatness, and traits system. Always those and a few small related things (rarely anything new).
But at the end of the day, you look forward to the game because it will have surprises left. It brings a certain level of anticipation to the table that the game would lack if we knew every nuance beforehand. While there are questions I would like answered beforehand that have more to do with custom content creation than gameplay, I think anticipation can be a good thing. I just wish my anticipation had been rewarded for February instead of moved back to June.
Ah well. We'll live, won't we?
