I don't understand why SOOO many people disliked ODST. Sure the campaign was a little short, but once you get over that, it's one of the BEST Halo games in the series. Not counting the trilogy as a whole, ODST has the most memorable and impactful storyline out of any of the games. The characters in ODST were also the only ones in the series that I really felt attached to. ODST also had a better firefight than Reach. The ONLY problems with ODST are the lack of matchmaking, lack of attention from Bungie, and the pricetag M$ put on the game. In my opinion, it was WELL worth the money, but others didn't see it the same way. ODST was more or less a field test, (as Bungie saw it), for Reach. Bungie has always seen it as an 'expansion'and not a full game itself; had they put more time into expanding ODST, it would have easily been THE BEST game in the series. Why didn't Bungie take some good lessons from ODST and put them in Reach?
I can't wait, the very first thing I'm going to do when I get break from college is go back home and play ODST. Prepare to Drop, t-minus 21 sleeps and counting.
