Dragon’s Lair was a arcade game that used revolutionaly technology by using massive discs to output video. It was the grandfather of quick-time events. The game received a sequel and spin-off known as Space Ace, both didn’t do so well due to the Video Game Crash of 1983. The original game got so successful that it recieved many ports, most infamously, the NES version. As technology evolved, we got the console versions, the Steam version, and this version.
The iOS version is not very good. Even though the entire game plays exactly like the original, it seems that the window of when to hit the correct button is offset from the video, resulting in cheap deaths. It would be cool if there was the ability to play the infamous drawbridge scene, but that most likely will not happen since this game hasn’t been updated in years.
If you’re looking for a good port of the original Dragon’s Lair, this is definitely not one of them. I would suggest playing the console versions or the Steam version of the game.
