The document summarizes and analyzes research on existing side-scrolling and top-down video games. It describes common features across multiple games such as simple colors with little shading, side or top-down viewing angles, and an absence of complex shadows due to the simplistic designs. The research will inform the development of the author's own game, which will be played from the side view, use simple textures, and omit shadows to match the retro, low-fidelity style of the analyzed reference games.
