Perhaps the other review of this game is talking about the zx spectrum which is very different from the original arcade classic.
RASTAN is an all time great scrolling fighter game and amazingly, retains some playability even today.
In terms of pixel count the game was fairly blocky compared to its peers but what it lost in resolution it made up in colour and imagination. The scrolling landscapes were both atmospheric and awesome, every sprite a gem. Minotaurs, centaurs, harpies; an array of mythological beasts and even Teutonic style armour clad knights. Every level was split into a landscape followed by a castle which ended in a boss character. As I recall it had 6 levels but would not let you replay the last level with more money, you just had to start from the beginning.
The crowning glory of Rastan was the music. It was moody, subtle; mad and frenetic, all at the right times and always perfectly in keeping with the fighting fantasy theme. The music while not containing anything you could hum later was like a film score in that it added to the drama and heightened the tension.
OK before I go all hyperbolic on what is essentially a simple blocky platform game lets put this into context. If you look at arcade gaming history and place Rastan alongside other great fighting platform games it ranks in the top 5 easily and for my money takes the number 1 slot.
It was a highly playable masterpiece of arcade gold and even today I can fire up my emulator and hack away at a couple of games thinking that it ain't half bad for an ancient game.
Hooray for Rastan a golden oldie classic.
