I Feel Like I Should Be Buying Things

Last night, Call of Duty: Modern Warfare 3 came out. I saw the lines outside of Best Buy and thought, "That could be fun," however, I wasn't thinking that about the game itself.
I looked at the people, sitting outside the store, bundled in blankets and multiple sweaters and I felt like I needed whatever they were standing in line for. Of course, I knew what they were waiting for, but the line could have been anything and I would have felt some need to bundle up and wait in front of that store.

I'll buy it and it'll probably sit on my shelf for a month.

It's really the only reason I don't go to midnight releases for games anymore. I've been to three in my life; one for the release of Halo 3, the others for Super Smash Bros. Brawl and Batman: Arkham Asylum. Each of those times, I knew I really wanted to own the game and that I would stand in line for an hour and half at a time when I could be relaxing at home. I usually never leave a store until 1 AM, so when it was my turn to get my copy of the game, I bought it and went home happy. At that point, after waiting for a while, I'm usually too tired to play.
You would think that'd I'd be disappointed at this, but I never felt that. I usually felt pretty content that I was able to purchase the game at all. Now that I look back on it, it was never about the game, at all. I realize that I was merely serving the need to be a consumer and it's one that I feel all too often. For instance, I heard that Best Buy might open at midnight on Black Friday. I don't actually need to buy any gifts that won't be on sale throughout the month of December- or that I could find online for cheaper- but I might go for the sake of going.
What the hell is wrong with me?
Whatever it is, I really do want to play Call of Duty: MW 3 and Battlefield 3; I really just need to figure out which one I want to buy first.
