It's certainly worth it. The Amiga version might have better graphics and music.
The game itself is time based so certain events happen at certain times and is quite advanced when it comes to gameplay. If I am not mistaken it can be finished in multiple ways and it's even possible to mail evidence to the police. Though it might be a little hard to play and certainly doesn't play like modern games. You might want to save every now and then, or restart sometimes.
