Because Rockstar needs to recoup huge production costs.
文章： Jonas Maki – Gamereactor.cnWhen Grand Theft Auto VI finally releases, likely next year according to several sources, it will likely be a candidate for the most expensive game ever made. Not only is the development time long, but it also involves a huge team and production values are expected to be through the roof.According to the websiteNiche GamerAccording to reports, development costs are as high as over $2 billion, which will be reflected in the game’s price tag, which is actually $150. Since most gamers have complained a lot about the rising prices of video games this generation, we don’t think this would please everyone if it were true. However, we’ll submit this rumor to the “Highly Unlikely” section because it doesn’t make sense. Fewer sales isn’t good economics either, and Rockstar needs a lot of people to play the multiplayer portion of the game in order to be able to make a lot of money from microtransactions. Basically, we doubt this is true, even if we don’t rule out a smaller price increase for the game since it was so expensive to develop and so popular. Would you buy a $150 game?
