The document describes various probability distributions that can arise from combining Bernoulli random variables. It shows how a binomial distribution emerges from summing Bernoulli random variables, and how Poisson, normal, chi-squared, exponential, gamma, and inverse gamma distributions can approximate the binomial as the number of Bernoulli trials increases. Code examples in R are provided to simulate sampling from these distributions and compare the simulated distributions to their theoretical probability density functions.
The document summarizes the structure and history of the visual novel game industry in Japan. It finds that visual novel games have a uniquely large narrative volume for their production cost compared to other media like novels and manga. Many visual novel game developers started as doujin (hobbyist) groups, and the industry serves as a talent pool for other media. The visual novel format is well-suited for producing epic stories at low cost.
1. In the 2000s, the handheld game console market reversed and surpassed the home console market due to soaring development costs for home consoles.
2. Mobile phone games became popular around 2003 when QVGA liquid crystal displays became common, though the non-social game market was saturated by 2010.
3. Japanese game companies struggled to enter the online games market, while their games did not sell as well overseas and the country lost international competitiveness in the game industry.
The document discusses the origins and evolution of Japanese role-playing games (JRPGs). It notes that while the first Dragon Quest games are difficult to define as JRPGs, they were an important milestone that helped popularize RPGs in Japan. The document then outlines the early history of RPGs in Japan in the 1980s, including the localization and simplification of Western RPGs (WRPGs) to make them more accessible to Japanese audiences. This "easiness revolution" helped establish JRPGs as having simpler and more narrative-driven designs compared to mechanically-focused WRPGs, leading JRPGs to diverge and evolve into their own unique genre over subsequent decades.
