Ok let me break this down since people are posting that $100 is too much for a game.
Collector's Edition - $79.99 (No one is putting a gun to anyone's head to get this version but I want the extra goodies)
Standard Game - $49.99
Strategy Guide - $19.99 (This is an optional item and I am mainly getting it for the maps)
Tax - 8.25% in Texas
My total cost breakdown:
Collector's Edition $79.99
Strategy Guide $15.99 (Get 20% off when buying the game and guide together)
Price in Texas for just the standard game after taxes: $54.11 (Same as most other games) The price for the Collector's Edition is $86.59 - that is roughly $27 more than I paid for Doom 3 and I guarantee I will get more time out of this game in the first free month of game time than I ever did with Doom 3.
That ends today's lesson in Economics101. The Collector's Edition of this game costs the same as the one for Half-Life 2 by the way.
Have A Nice Day!
