>I mean no, integral came out after the western release so it probably has unnecessary changes as well
Looking it up, you're correct.
Integral (With the PC version is a port of) includes all the changes made to the Western release, with the exception that it also an exclusive commentary file from the dev team and the VR missions included on a seperate disc.
So, I stand corrected, the only way to experience
Metal Gear Solid as it was intended is to play the original release, or
Twin Snakes (Either way, you need to shell out money to by VR missions seperately, if you want the complete package).
