Heroes of Might and Magic IV

Opposing Force: Enlightened - a mod for Half-Life: Opposing Force that adds a lot of new weapons, improves lighting, effects, and atmosphere of the original campaign, making it visually more modern without changing the storyline.

Half-Life: Extended is a large mod for Half-Life that expands the original campaign by combining content from Blue Shift and Opposing Force, adding new levels, reworking NPCs and maps, and increasing world detail. The campaign has become larger and more varied, making Half-Life: Extended feel like an almost entirely new game.

Generals Alpha — a total conversion on the OpenRA engine that aims to recreate Command & Conquer: Generals as close to the original as possible, but using developments and resources from Red Alert and Tiberian Dawn.

The Elder Scrolls II: Daggerfall Unity is an unofficial remake/port of The Elder Scrolls II: Daggerfall on the Unity engine, which makes the game compatible with modern systems and hardware, fixes old bugs, improves graphics, adds convenient features, support for high-resolution screens, mods, and localizations.

Half-Life: Dreamcast — a PC port of the unreleased Half-Life version for the Sega Dreamcast console. This version differs from the original and the later PlayStation 2 adaptation: it features modified levels, unique NPCs and objects not found in other editions, altered difficulty levels, and numerous hidden references to Dreamcast.
