generally, if it's a series that i'm new to or know it to be a difficult one, i set it to easy. if it's something i've become familiar with or know it to not be strenuous, then i'll go normal. i never play hard bc i'm an actual weenie. the only games i would ever put on a hard mode is pokemon bc i'm good at them and know wtf i'm doing, lol. but you know, we don't have that option sooo.
