On a different note Hosfac is right, they can't just rehash the Sims 2, but at the same time if they leave too many of the old gameplay mechanics out, people will stop buying it. You just have to trust that most of what you loved will come back and that very little that you didn't like will stay out, and hope that your opinion is closer than not to the general public's.
Actually, WA and Ambitions pretty much included nothing from the previous versions, and it sold extremely well. The key to introducing old concepts into the new game is making them into something new. The Late Night clubs are completely different from anything included with Night Life from Sims 2 and Hot Date from Sims 1, and the vampires are different as well. Even celebrities are different from the Superstar expansion from Sims 1. Pets will have to be different as well, or else it won't do as well as the previous expansions for Sims 3 have done. If I want the same old stuff, I already have Sims 2 installed on my computer and don't need to buy it again.
Despite their popularity, I didn't like the previous two pets expansions. I found them to be infinitely more trouble than they were worth. However, it now looks as though pets are going to be a bit more enjoyable, and even I am looking forward to this expansion.
Also, it was eating at me all night that everyone was saying it was too soon, but it's E3 people. They would get laughed out of there if they only brought a stuff pack to show off, and they were nice enough to release Generations now, so what were they supposed to do? Just not show anything? Wouldn't you feel ripped off if they hadn't shown it off?
I absolutely agree with you. E3 is the Superbowl (or World Cup for all of our non-American members
) of the gaming industry. When you go to E3, you need to drop a serious bombshell, and EA did exactly that. It's likely that the timing of the release of the pets expansion was intentionally timed so that they
could drop this bomb there and steal the show.
The release of the Pets expansion is a good ways off. It's not going to have any affect on Generations.
