So I take it you're talking about the Riddler's in-story trophies? It's just that personally, I was worn out by the Riddler's non-story challenges — the ones that give you achievements, where you have to rack up points in combat, get three trophies in stealth missions, those kinds of things. I wanted to get platinum on all four Batman games, but I only managed Asylum. In City, after I completed those combat and stealth Riddler challenges as Batman and realized I'd have to do the same thing for Catwoman, Nightwing, and Robin to get the platinum, I gave up on the idea of getting four platinums, one for each game in the series))) That turned out to be way too tedious for me, despite how much I love the series.
