Reminds me of when I tracked some bug in linux game (don't remember the name) to some fs call on xfs not returning what game expected, and it only happened if you had "old" (formatted with some older version) of XFS.

There was separate problem with some games borking out if your FS returned 64 bit inode.

There was also a swath of bugs with Unity games crashing or behaving weirdly if your locale didn't had same numeric separators as default one,

So if say, your locale printed 0.0 as 0,0 game didn't work till you changed environmental variables to use english or C
