One of the best ways to tell a game you love it is to play on the hardest difficulty. It's a show of commitment, a sign of willingness to learn the in's-and-out's of a game in exchange for an engrossing challenge that'll blister your thumbs and rattle your brain. And only a select, dedicated few ever attempt such a feat - let alone succeed. Just look at any global achievement or trophy rankings if you don't believe me. Hell, most players don't typically finish the game in question, regardless of difficulty.
