I don't know about for the better. The very first game is still far and away my favorite in general. The redefinition really changed what it was about on a fundamental level. Obviously redefining means redefining, but the series just provides a whole lot more now than it ever did, and the games don't compare at all in those regards. But for the raw fun of just driving around and doing missions, for the style and the craziness, and the memorable uniqueness, the first still wins in my book.
