For instance, high costs and instence competition make it very difficult to enter the video-game business. The barriers to entry for this business are extremely high given that today's average video game takes 12 to 36 months to create. $10 to $20 million to develop, and teams of highly paid creative workers to develop realistic graphics, captivating story lines, and innovative game capabilities, who must also be disciplined enough to meet budgets and very strict deadlines and still produce efficient, reliable, bug-free code. These barriers to entry are also in place for online video game, like ACTIVISION BLIZZARD'S World of Warcraft, which are growing even faster than traditional video game. Regarding online gaming, industry analyst Arvind Bhatia says, "This is a very hard and expensive market to enter, let alone be successful".
