If so look at this

I just love how detail oriented Oblivion is, it's wonderful how you can drop something and it looks like it's falling in real life with regards to how the designers calculated how items would lay on a rock, or whatever object it may land on, due to it's weight and the gravity pulling on it and what not. Also, it is wonderful that there are several different ways you can play through the game.

In a similar light there is Vampire the Masquerade... while it is not nearly as detail oriented as Oblivion it does have several ways in which you could develop your character (different character builds) and then you can play through the game just as well as another build BUT how you go about engaging in combat and completing your quests throughout the game can be very different, if you go from one person's character to anothers.

I wish that more time and love went into games, like the attention that had to go into the above aspects of said games, it makes for a much more interesting experience.. and is much more enjoyable and increases the replay value to me. *sigh*
