Just finished it! It was awesome!!

Massively impressive game, the way they kept introducing new gadgets, the number of 'Holy shit how amazing is that?!' moments, combat, stealth. Loved it. Really looking forward to the sequel.
And I cleared the first playthrough getting all 240 riddles, plus the Arkham diaries, all without using the internet (despite what the Riddler thinks

). It was a game that was paced really well, you could just follow the story or decide to chill out and collect the trophies and audio logs. Hope they do the same for the next game.
Though the completionist in me doesn't want to stop. Want to do it again on Hard mode (just not right now), pick up a few achievements attached to the story that I missed and get full medals for all the challenges, preferably without video walkthroughs.
