Unreal Engine (UE) is a 3D computer graphics game engine developed by Epic Games, first showcased in the 1998 first-person shooter video game Unreal. Initially developed for PC first-person shooters, it has since been used in a variety of genres of games and has been adopted by other industries, most notably the film and television industry. Unreal Engine is written in C++ and features a high degree of portability, supporting a wide range of desktop, mobile, console, and virtual reality platforms.

Cesium is an open platform for creating beautiful 3D topographical maps from aerial photographs (photogrammetry) and from 3D global data. Cesium provides the fastest available tiling pipelines for streaming game content as 3D Tiles.

Steam is the ultimate destination for playing, discussing, and creating games. Steam started as a multiplayer gaming platform and multiplayer has always been a huge focus. Steam provides many different features and APIs to improve the multiplayer experience.

Unreal Engine 5's revolutionary World Partitioning system is a game changer for building massive open worlds. By dividing game worlds into modular streaming chunks, developers can now create persistent environments of unprecedented scale, allowing the creation of virtual societies while optimizing performance. World Partitioning works by splitting game worlds into a grid of partition cells that can be individually streamed in and out. This allows worlds limited only by disk space rather than computer memory.
