If you can show me where to get that superplay video, then I'll watch it and amend the review accordingly. The only reason I gave Rastan 4 instead of 5 stars was because I thought the game was unfair. I don't mind hard games--in fact, I respect them and enjoy them very much. Dodonpachi Dai-Ou-Jou is one of the toughest games I've ever played and I'd give it 5 stars any day, regardless of the fact that I still can't get past the 3rd Stage (I am working on it though!)
Ghosts 'n Goblins, on the other hand, is an example of a game that is unfairly hard. I will always mark down games that are unfair, regardless of their other qualities.
Now, what distinguishes a very tough game from an unfair one is a bit tricky to pinpoint. The main thing is that it must be possible to advance with a reasonable amount practice. What constitutes "reasonable" is subjective, of course.
In any case, there's a couple more things I'd like to add to the review, so link that video when you can. I'd certainly love to see how he can finish the bosses without getting hit.
