Ars Technica's Opposable Thumbs blog takes a look at the numbers for last year, and makes an interesting observation: hardcore gamers are probably not the future. Specifically, last year's videogame sales numbers show a huge trend in the adoption of mass-market licensed games. We've also previously discussed the extreme popularity of casual games. Despite Gears of War selling around the same amount as Cars (both around 2 million units), the cost in time and money to create Gears was substantially greater than the cost to create the Pixar-licensed title. The result? "As growth continues, we're bound to see some substantial changes. As it stands, hardcore gamers are still a pivotal purchasing force in the games market: most of the top ten titles were what I would consider "hardcore" games. However, the trend away from the hardcore and towards the casual is becoming increasingly more predominant. We've talked quite a bit lately about the growing demand and response for casual games, and when coupled with the shocking sales of licensed products, I'm left wondering whether or not the number of hardcore gamers is dwindling."
