Cooking Mama 2 is by far superior to the original game, even though it doesn't depart from its roots. The Sims 2 remains one of my favorite PC games of all time. Disgaea 3 looks awesome and I can't wait to play it.
Then again you have non sequel games like Valkyria Chronicles which I really liked, as well as Etrian Odyssey and The World Ends With You. All J-RPGs from different companies, and all non-sequels. In my opinion they are all good games, the three of them, since they are not remakes of previous games and add something new to the old formulaic genre.
At the same time as this you have the Four Horsemen of the Apocalypse, that is, games with Four in the title which re-jig a lot of the original game's structure, but still stick to a standard formula. Street Fighter IV is an example of this, but a more extreme example is Grand Theft Auto IV. These games are a mixed bag because some are good (Street Fighter IV) while some bad (Grand Theft Auto IV, I have played it and I didn't think it nearly as fun as San Andreas. Not to say the new story mode is bad).
Then you get into territory like Phoenix Wright: Ace Attorney where the first title is so innovative and new that you love it, but all the sequels feel like rehashes of a newly exploitable formula.
