Arkham City. Gameplay was fine, I didn't like the constantly respawning gunmen who would always be on your case when you were trying to explore, and I don't think the city was very easy to get around in. The predator segments were also less successful than Arkham Asylum in my book
What bugged me the most was the story/game environment though. I've compiled a list of inane questions about a fictional universe for your enjoyment though.

1. Why is Strange so intent on building arkham city and then killing all the inmates? I realize that he was being manipulated by Ras Al Ghul, which leads to...
2. Why is Ras Al Ghul so intent on building arkham city and then killing all the inmates? Why is his headquarters directly underneath a giant prison?
3. Why is Clayface working for Joker? Why did he take the antidote rather than having the actual Joker take it?
4. Why did the Gotham city council allow their police department, natural history museum, courthouse, and industrial district, among other things, to be part of arkham city? Why wouldn't they leave important stuff on the outside and use the slums or something as the prison?
5. Why is half the city falling into the water? Earthquakes in New York? Sorry, "New York"?
6. Why are the museum and a nightclub known for its prominent criminal presence part of the same building? Moreover, why is there a giant room full of water between them?
7. Why is Nora Fries in Arkham in the first place? She's very difficult to move or store. Maybe she was the to start with, because why would anyone smuggle her in?
8. What type of prison includes wide open access to a major body of water as well as functional and unprotected boats?
Arkham Asylum had a simple but well paced and told story within a logical and well designed space. Arkham City's story was simply an excuse to string as many villain appearances as possible together in a space constructed to string as many Batman references as possible together. I only played four games this year, but even with Skyrim's many bugs, this game just didn't impress or amuse me that much
