hello, i have finish simon the sorcerer 1 nad 2 years ago on amiga system. i would like to buy them again but i dont know if those version on the site has more content. also how about voice? does they have?

Not sure if it has more content, since I haven't played much of it yet, but it does have voices.

The Amiga versions of Simon the Sorcerer 1 used difference music, compared to the PC versions. The only other differences would be sound effects and speech, if you only played the Amiga disk version.
The Amiga version of Simon the Sorcerer 2 had the music disabled, and the animation shown via the F10 key was different.
