All Amstrad owners will remember Sorcery. It was the first game to really show what an Amstrad could do incredible graphics and animation, split screens, you name it... it had it.
Sorcery Plus is the expanded disk version of the game. Using overlay techniques (i.e. only having the chunks of program in themachine that you are using at that one time) it is possible to have a program that takes up the entire disk. I don't know if Sorcery Plus does fill it all up, but it certainly is very big.
The continuous disk accessing could be annoying, but the Amstrad disk system is very fast and quiet, so that all you notice is a slight hesitation between the screens that need a disk read.
All his extra space is used to good effect. Chapter one is basically the same game as Sorcery, flying from screen to screen trying to save all the trapped sorcerers in an advanced action/problem solving (adventure) environment. The graphics are suitably high resolution on the top and bottom halves of the screen, keeping detail where it's needed and coour where its effect is best.
Sorcery Chapter 1 comprises 47 screens, but the real plus (ho ho ho) is the extra 28 screens of Chapter 2. In this section, you must defeat the necromancer, this will give all those people who completed Sorcery something else to aim for.
Sorcery was the best Amstrad game ever. Sorcery Plus is better.
