The jump to full 3D makes Sims 2 the best looking Sims game to date. Character customizations are as deep as ever, giving players the option to make their Sim look exactly how they want them, right down to the smallest dimple. Those who just want to jump into the game can choose from a variety of pre-made body parts while perfectionists can morph individual traits to get things just right. If you can't make your Sim look exactly how you want there's no helping you. Clothing options feature much more variety and range from ultra chic' to ultra sexy. There's also a few silly options throw in for those of us who like to make their Sim as strange as possible. The new 3D models also allow for more range of emotions on the Sims. The new graphics also make those little thought bubbles much easier to read, taking much of the guess work out of tending to your Sim's needs. Animations are smooth and expressive which really helps to push the pantomime used by the characters to communicate to a new level. Environments also share in the graphical bump.
Sim-speak has been expanded a bit. While you still can't understand a word of what they are saying (which is the point), it now sounds like more of a language instead of a bunch of gibberish. Sim-speak also features more expression in character voices, adding to the feel. Music is kept in the same tempo and tune as the previous game.
