Summary: Played it all the way through, and I found it to be the most confusing of all the Halo games. Only after endless wandering does the game put up an arrow for direction. An easy fix for this would have been to have a directional hash-mark at the top of the screen on the compass heading. Most of the other Halo series allow you to move about, but they keep you on a direct path, this game is wide open, it's easy to get lost.
Summary: Well, let's start from the ebay experience. I bought a redemption code card because I really dislike having physical discs and just wanted to download it to the 250GB hard drive that's built into my Xbox. The card came very quickly, in a purple envelope, with handwritten addresses on the front. I thought it was a Christmas card from someone I didn't know, or at least didn't know the real name of.
