Wow. Batman: Arkham Asylum is fantastic. What a prime example of a game of sweeping quality from end to end (possibly prematurely stated, as I am only about three quarters of the way through the main game). It is clear that the developers have worked hard to create a solidly great game that does justice to the Batman universe. The combat system is fun and fluid (Prince of Persia ( 2008 ) take note on how it can be done right). The stealth components are pretty cool. The detective work (including riddles) adds diversity. The locale is creepy, with great touches of detail. The balance of linear plot vs. freedom to explore is well-implemented. The collectibles, in the form of character bios, trophies, and interview tapes, are rewarding. I never imagined, back in the days of previous console generations, that I would ever be playing games of this comprehensive awesomeness. I don't quite understand the arguments of those who say that gaming is going downhill this generation. I'm enjoying games more than ever.
Requisite nitpick: While the Joker and others are loose, innocent people on Arkham Island are dying. So, why the hell would Batman waste even a minute trying to solve any of the Riddler's riddles? Maybe this side-story could have been enhanced if Riddler had a hostage whom he would kill if Batman did not solve all the riddles. (I know. I know. "It's just a game." Plus, I admit it. I like the extra challenges. :) )
It's games like this that have all but killed my interest in movies. I'm not saying that games surpass movies in every respect. They don't, particularly not in the areas of acting or writing... In general... Yet. ;) I'm saying I get swept up in games like Batman: Arkham Asylum in a way that I no longer do by films, since films lack that interactive component to yank me in.
