How is that even possible when other, newer games take up less than a quarter of that? I'd attach the clip I took of the download window, but, perhaps ironically, this website has a size limit of 400 KB for files.ĪRK is big, like really, painfully big, but if it's using up 400 GB on your machine then either you've subscribed to a lot of mods or there's actually something going wrong on your machine. I'm sorry, am I doing this wrong? How can this game take up almost half of a terabyte of space? 400.84 GB of space required.
