Airwolf Video Game
Trying to navigate your high speed military helicopter through tight caverns would be difficult at the best of times, but the awful control system in the game made it a very frustrating experience. Add to this, trying to avoid falling spherical objects, enemy cannon fire and lasers in a tight cave (while at the same time firing at brick walls to create a way through), and you had a multi-tasking nightmare and one hell of a difficult game on your hands. In fact, it was a brutal game, and you needed a ridiculous amount of precision to complete it.
The BBC version was particularly bad, with ghastly colours and far too much gravity on the helicopter. Whilst the C64 version's graphics were probably the best of the bunch, it's control system wasn't a lot better.
