I'm still trying to catch up on last year's game releases, thus I've only just finished Arkham City. It’s a great game, and I can't stress how fun it is to play, but It feels watered down compared to Arkham asylum. The overarching issue that I have with Arkham city is how it has too many brief appearances. Multiple enemies get only a tiny bit of screen time, and several are barely mentioned. One or two faces are around long enough to feel fleshed out, but that isn’t the case across the board. For me this made the villain experience less potent. I don't really want to rant on, but suffice it to say there were too many villains fighting for screen time. In the end I didn’t' feel any one of them was a serious threat, and was left wishing for the more focused experience and quality of the original Arkham asylum. I suppose it come with the territory though, the perils of trying to follow up a fantastic game.
P.S. If you guys want me to go into more detail I could make a video about the game. Let me know what you think in the comments.
