1) Riddler questions ---> in the back menu, I'm trying to understand what the icons mean for some of the riddler questions .. There's a *3,*6, *9, and then next to that there's a final icon ... What are those?
2) more riddler questions - when a question pops up during the game, does that mean I'm near to the answer?
3) new game + - if I haven't done all the side missions yet, and I start new game plus, can I go back to the "old" (easier) game and do more side missions/riddler trophies? and will they be mirrored in new game plus?
