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.
