No, I like action games. I'm just saying there's a point at which increased difficulty doesn't contribute positively to the experience for me. I don't mind a learning curve. I don't mind realizing I've underestimated the difficulty of a particular game mechanic or boss or level. I'll play at normal difficulty or hard, depending on the game. But if the essential game mechanic is just being really hard and unforgiving, it's not a game to me anymore. It's just a frustration engine and a time sink at that point.
I spent my youth playing the same Nintendo and Super Nintendo game levels over and over again, like notoriously difficult Battletoads levels, and the satisfaction of finally getting it after fifty tries just comes in increasingly diminishing returns. I guess I like games that make me think more rather than just react faster or memorize boss behavior formulas.
