A Quick Tip by SolidusSnake
I'm pretty late on this one. Arkham Asylum is one of the rare games that is universally praised by everyone, and for damn good reason. I stayed away from it cuz, well, superheroes are kinda lame, but finally Doomrider talked me into playing it, and I'm glad he did. It's damn sweet, and even if you think superheroes are completely lame and for dorks, you should still play it.
It's got some of the best beat-em up gameplay I've seen this gen, jumping into a crowd of thugs and beating the crap out of them never failed to put a smile on my face. It's got amazing stealth missions. You sneak up on guards, swing from gargoyles with your grappling hook, glide down towards unsuspecting mooks, and jump out from floor grates to kick ass in these segments. All the while your enemies are freaking out and Joker is mercilessly taunting his own henchmen. It's got exploration. There are tons of secrets on Arkham Island, and Batman has all the tools he needs to find them. The grappling hook, in particular, is a great feature and adds so much flexibility to your movement and to your offensive and defensive strategies.
But the best thing about the game is that it captures everything that's entertaining about the Batman mythos. The story knows when to be serious, and it knows when to invoke the comic book campyness that Batman is famous for. Joker's trollishness is hilarious, and how can you not laugh when a thug asks Batman why he isn't busy getting a cat down from a tree? Several of the big supervillains from the Batman universe show up as enemies, but even if a villain doesn't show up in the flesh, you can count on them appearing at least as a character bios. It gives you the impression that, while the game is great and full of surprises, there is still a vast world and a huge number of colorful characters left untapped. Best of all, you get Kevin Conroy as Batman and Mark Hamill as the Joker. These guys played the same role in the fantastic Batman animated series from the early 90s, and they are PERFECT for their respective roles. Mark Hamill in particular completely owns the character of the Joker. Anyway, this was a great game, and now I'm so fired up for Arkham City I can't even believe it.
