A video game remake is a modernized adaptation of an earlier title, created to update graphics, gameplay, and technology for contemporary hardware and audiences while preserving the core story and fundamental concepts. These remakes are often developed by the original creators or by fan communities (known as fan games), and they may significantly alter dated mechanics—for example, the 2019 Resident Evil 2 replaced the original's tank controls and fixed cameras with an over-the-shoulder perspective, while Black Mesa rebuilt Half-Life from scratch using the Source engine. Historically, early remakes were called "conversions" due to hardware limitations, such as Midway's 1975 Gun Fight (a microprocessor-based version of Taito's Western Gun) and Atari's 1980 Space Invaders for the Atari 2600, which became the first console "killer app" by quadrupling system sales. Another early example is Warren Robinett's 1980 Adventure, a graphical take on the text-based Colossal Cave Adventure. By 1985, Sega released arcade remakes like Pitfall II: Lost Caverns, which reimagined the home game with new levels and graphics, marking a shift toward intentional nostalgia-driven remakes. Ultimately, remakes aim to make older games marketable to new audiences, often blending familiar narratives with contemporary design conventions.
