It's funny you mention Arkham Asylum, because I just wrapped up another playthrough of Arkham City, and it has similar problems to what you just mentioned.
Now, I will say that Arkham City does a great job explaining the controls and how you do your gadgets, so that's not the problem here. The problem is with those Riddler trophies. Oftentimes, they require the player to know how to exploit or utilize certain quirks with the game's engine in order to complete them, and oftentimes those quirks are learned through trial-and-error. This isn't completely a bad thing, but the problem I've run into are very specific incidents where a certain gadget trick or quirk was need that's used no where else in the game and sometimes leaves you thinking "Oh, I didn't know this gadget could do that."
This is made even worse when compounded with all of the things done right with Arkham City. Too many times I felt that the only real reason why I progressed through certain challenges was because I've already done them already, leading to a bizarre situation like in The Mummy with Hamunaptra, a place that apparently can only be found if you're been there before.
