I got the PS3 version, because I don't have an Xbox either. It's supposed to come out for the PC, but the PS3 version is fine for me.
I got passed the part with Joker's Henchmen abducting the doctors, and now I'm on the part where I have to find Doctor Young's files on the venom formula. I've been running around in circles for a while. I rescued the guy that has the hook on his hand and that's where I'm at (I forgot his name...). I'm taking a break from it at the moment, because like I said in my post, it hurts my eyes to read the text. Yeah, I play with text on, just so I don't miss anything
You get all the Riddler trophies? I know I missed a lot of them. Can I go back on my second playthrough and collect the remaining ones, or do I have to get them all over again?
