– A functional PC game like GTA: Vice City requires hundreds of megabytes (even stripped down). A 10MB file cannot contain the game; it would almost certainly be malware, a fake downloader, or a corrupted archive.
A version typically includes a patched .exe file (like gta-vc.exe version 1.1) that resolves these save-game and audio issues. However, a 10MB file cannot contain these fixes alongside the game data.
