How is the new Steam version? Did they change anything? Did they ever change the god-awful Midi audio format from the original PC version, or do they use MP3's like on the Playstation?
They uses OGG music files, it's no longer the midi version but not the original as well. There is a "Patch" for replacing current OGG to original soundtrack (Playstation Version) OGG
The graphics are about the same but re-done to be compatible with high screen resolutions.
There is an achievement system but to be honest, it's there just to fill a special feature list.
Thats about it.
