I should also consider the technical steps involved. If someone is using a repack, they might need a script to remove unnecessary files and replace them with compressed versions. Maybe using a tool like WinRAR with maximum compression, but that doesn't remove data. For a true compression without loss of functionality, you need to edit the game files.

Next, I should consider the tools and methods that game developers or fans use to compress games. Maybe they use something like 7-Zip, WinRAR, or specific game compressors. Another angle is remastering or repackaging the game with only the essential assets. But how feasible is that? Let me think—GTA SA has a lot of textures, models, and scripts. Removing non-essential assets could reduce size, but you have to ensure the game still works.

First, I should check the size of a standard GTA SA PC install. From what I remember, the PC version is around 2GB. So compressing that down to 200MB would require significant compression. The user might be referring to a pirated version, but I can't promote piracy. So I need to approach this carefully. Maybe there are fan-made mods or tools that allow for smaller versions of the game for testing purposes.
