I play fighting games so Rank is already very hard mode...
Jokes aside it depends on the game, for the more casual games i'll do hard/ very hard but for the really tough gruelling games I'll do normal/ hard. I rarely play shooters but if I do I'll play on normal because I suck at them lol.
Playing a fighting games is stressful enough as it is so when i play a single player game i just want to relax but with a little challenge.
