Notice how much games changed?
Like for example Tomb Raider :

• in the old game her chest is a geometric shame ...somthing like a triangle.
• in the new game wow...3D baby, no more 2D models.... and now you can fully enjoy the wonders of....well... "Boobies" (Im 5 years old I know hi hi) .
  But in my opinion 2 D is perfect on a game like dungeon siege 2 ....it just looks awesome for any year.
  PS: DOOM is the same like deungen siege...you can play it any time ...because it is just so awesome and fun!
