A 461 GB "extreme rip" version of GTA 4 seems highly unlikely, as it would imply that the game has been significantly expanded or modified, rather than compressed. I couldn't find any reliable sources or reports confirming the existence of such a massive rip.
The 461 GB wasn't just the game. It was an obsessive, hyper-realistic overhaul. Every single texture in Liberty City—from the grime on a Star Junction billboard to the individual pores on Niko Bellic’s nose—had been replaced with 8K photogrammetry. The "redundant" audio files had been replaced with 24-bit lossless recordings of actual New York City streets. But the real weight lay in the "Neural Life" folder. gta 4 extreme rip in 461 gb full
