Injustice is great, I'm reviewing it and love it. It is dark, but DC don't have a problem with dark as long as it's an alternative world. Remember in a JLU episode Justice Lord Superman lobotomised Doomsday. Sometimes it doesn't even take an alt reality (Barbara Gordon in Killing Joke)
Also making my way through the Blackwell point click adventures. Two down so far, really good, and pretty short too.
