Realtime Software‘s classic Carrier Command is an early real-time strategy game that first came out for the Amiga and Atari ST in 1988 through Rainbird Software. In it you control a futuristic aircraft carrier battling for domination of a group of islands with an AI-controlled enemy carrier.
The ZX Spectrum version of Elite was developed by Torus and published by Firebird in 1985. There were 48K and 128K versions made available and both are excellent.
Realtime Games‘ 1988 hit, Carrier Command, is a compelling mixture of 3D simulation and real-time strategy.
In it you take control of a futuristic, robotic aircraft carrier and must work your way through an island archipelago, taking control of each island and competing against a rival carrier.
