I apologize if this is already answered somewhere but I'm curious what exactly a fitgirl repack is? I know it's a pirated version of a game but like is it just an installer or something? And if you imported the game into steam for example can you be "banned" or VAT (idr the term)
As someone who only recently moved to somewhere with gigabit internet. At 15Mb/s (mind the mahoosive difference between megabits and megabytes), I can say I very much prospered from the significantly smaller repacks, not to mention the ease of mind of knowing my games were coming from a safe source. That said, even when living in the geographical 90s, my hardware was still competent. Even when I was running an i5 3470, I never encountered a decompression + installation time of more than 3 hours. I'm now running a hexacore Ryzen with 32G RAM and would struggle to use a whole hand for the amount of times I've spent more than a couple of hours on a Fitgirl installation so I'm not sure what you're doing wrong but it's not the repack.
