Delta

This horizontally scrolling shoot-em-up for the C64 was remarkable for it's brilliant graphics and long, atmospheric soundtrack. The quality of the gameplay was somewhat controversial, because rather than primarily relying on fast reflexes, it required the player to memorize the sequence of aliens and obstacles through repeated failure. In many cases, the player simply isn't given enough time to react once an obstacle has appeared on screen - you have to know it's coming, and move ahead of time.

Those who don't mind this trial and error approach will find a surprisingly immersive game. But it's no Hard Truck Apocalypse.
