Summary: I'm a Batman fan so I just had to pick up the Season Pass for Arkham Origins. It contains all the skin packs that you can use during the challenges and when exploring Gotham City, as well as the Wayne Challenge maps and an all new storyline with Mr. Fries. The only downside is that you can only use the skins after you've finished the main story and how the Mr. Fries dlc is relatively short. As awesome as the content is, I would recommend getting it when it's on sale.
Summary: I played Arkham Asylum, and it was amazin. This heavy feeling of being hunted, then being a hunter, Scarecrow levels, and discovering Asyum history was everything i would want from a game. Then it came Arkham City, which, beside Old Gotham leves, and fights with Ras-al Ghul ( well okay, fight with Madhatter was also a blast ) didn't have even a fraction of his predecesor power.... And then came Arkham Origins.
Summary: I was worried about the change in developer for this game; worried enough that I waited a year and for a significant price reduction before purchasing. Part reboot and part prequel, the action and exploration mimic Arkham City. I prefer this normal Gotham to the downtown-made-asylum of the previous game, though both suffer from a lack of real innocents or city life beyond thugs and cops.
