^ I felt like I got a great deal out of ODST.
It contained all of the H3 map packs (none of which I had bought at that point, due to them being, well, overpriced
), it contained guaranteed access to Reach's multiplayer Beta, it contained Firefight - and the Singleplayer campaign didn't feel short to me.
Actually, between slowly but steadily working my way through on Legendary and searching for all the Audio Logs, it felt long enough to be sold as a stand-alone. And that doesn't even take into account my above-mentioned enthusiasm for the gameplay and combat mechanics, which really took me back to Halo: Combat Evolved in places.
