On that note there's a teeny tiny bash script called vimv, which enables you to rename a list of files in vim!
It's absolutely glorious, but don't switch lines around or delete them, it's really simple, comes with the full power of vim and doesn't protect you from yourself ;)
Individual games seem to top out at the 200 hour mark for me, with Monster Hunter world being followed by Elden Ring and 7 Days to Die.
Steam tells me it should be a little below 700 hours for Dark Souls 1/2/3 and Elden Ring combined, (with the uncounted hours on switch and others probably closer to 800 for the whole series)
But, I've easily got over 1000 hours in all Monster Hunter games across Wii, 3ds and PC.
