I'm not a Mod but, any talk of, or help with illegal downloads is strictly forbidden here. Having said that, the minimum system requirements for LCS are a PSP or a PS2, it has never been released for PC. I do remember seeing a mod to convert Vice City or III PC to LCS but it was still a work in progress. LINK
The graphics are slightly better than VC but less than SA mainly because it was made for PSP, and the story is about as long as III or VC.
Hope that helped. This post has been edited by Niall on Thursday, Feb 23 2012, 03:13
