Well, now you're talking like me. People don't get it, but I try my darnedest to beat a boss/level in single player mode[0] on the first or as few tries as possible so I don't learn it too much, because it 1) breaks the illusion that it's a game (it hurts the "experience" for me if the superhero gets a second or third chance) and 2) I like being pushed to respond quickly rather than replaying a script, and I consider it an accomplishment to beat a screen of a platformer for example on the first try.

Another set of games my girlfriend recently turned me on to are rhythm games, particularly VOEZ[1]. Again, as I don't think I said in the first comment but said elsewhere, it's not like I don't like the "classical music" style and I'm all "jazz music," but my "jazz" style is definitely my default mode. If you asked me afterwards to remember the notes, I would be able to tell you the gist but I certainly don't remember details, a lot of it is focusing when it gets complicated and responding on beat. And, as I said above, my absolute favorite is playing a song for the first time and trying to get a good score, because I really have no idea what's coming and it pushes my "respond quickly" buttons.

[0] not that you don't learn quickly/during the fight without dying, and as many games often are, there is an obvious hint of what to hit, the rhythm to a boss, etc.
