Now, solve this instance: Review: I was expecting Tomb Raider Angel of Darkness since last year, with a similar performance as Indiana Jones and the Emperor's Tomb, but now when I receive the game, I saw this little girl that walks like with an umbrella inside of her pants.The graphics and sound are great, but Lara rotates like a robot and when I try to make her run, she doesn't agree with me and moves extremely slowly.I have a 2MHz PC with 500Megas RAM and GeForce4 Graphic Card, and there is no possibility that only this game needs to practice Ctrl-Alt-Del each 15 minutes in order to play it.I'll find the way to sell my game and suggest Eidos to make a research in order to define how many of the customers are really satisfied with this game and determine if a refund to the customers is the better way to maintain the good image of Eidos until today.It's a shame.
