Arcadians

If Acornsoft hadn't stretched the boundaries of IP infringement we would not have arcade perfect conversions such as Arcadians (a thinly veiled Namco arcade Galaxians clone). In addition to the perfectly replicated gameplay, it also features an arcade-style high score table and a novel attract mode screen with a demo of it being played, just like a real cabinet, making it feel really authentic. Arcadians was programmed by Nick Pelling aka Orlando.
