Actually, I've been playing since TS2, and I'm kind of looking forward to the new GP. It adds some of the sci-fi elements that TS4 has been lacking in and it'll be a fun little adventure to take certain sims of mine on. And, hey, maybe some of the things added in this pack can actually be used to build our own adventure scenarios, so we're not just stuck with the one storyline. I'd actually like that, especially if we could upload our own scenarios on the gallery for other players to be able to play through as well. A whole genre of "build-your-own adventure" packs could come from this and add an new element to the game.
While I see where you're coming from with the frustration that, instead of making a story-focused spinoff title and focusing on improving the sandbox elements of the main game they made this, I don't think that this pack is inherently a bad addition to the game. Laundry? Yes, I think that was a bad addition to the game because I hate doing chores. An adventure scenario? Nah, I think it's cool because I love adventures. Heck, maybe the reason this pack is even being made is because the team originally wanted to make another story-focused spinoff title, but the execs at EA wouldn't approve the project unless they made it a pack for TS4 instead of a stand-alone title. Things like that do happen at media companies. Someone can go to, say, Cartoon Network and want to make a series about a teen genius fighting evil aliens with his insane inventions. CN takes one look at this project, the execs think it's cool, but they want to hedge their bets so they say, "Yes, but only if you can turn it into a Dexter's Laboratory sequel series." So, next thing you know, you have Dexter: Alien Wars, with a teenaged Dexter fighting evil aliens along with Dee Dee and Mandark. That's the entertainment industry.
