"Dune II," released in 1992, is credited with laying the foundation for real-time strategy games, featuring base-building and military maneuvers on the planet Arrakis. It has not been re-released due to licensing issues after Westwood Studios closed in 2003.
Interplay Entertainment released two video games based on "The Lord of the Rings" in the early '90s, allowing players to guide Frodo Baggins through Middle-earth. Low sales led to the cancellation of a planned trilogy, and both titles have since faded into obscurity.
"Star Trek: The Next Generation — A Final Unity," a point-and-click adventure from 1995, features Captain Jean-Luc Picard and his crew on a mission to recover an ancient scroll. It has not received a modern re-release.
Sid Meier's "Civilization II," released in 1996, has not been officially re-released, despite the series' significant evolution and availability of later entries. The absence of these formative titles leaves a gap in strategy gaming history.
"Black & White," released in 2001, is a god simulator that allows players to influence tribes on islands. It has not been optimized for modern platforms following the acquisition of Lionhead Studios by Microsoft, limiting access to those with original discs.
