No, if you pirate the game, you can't jump. People worked around it, but for a while it was delicious.
Correction, if you have no access to GFWL you can't jump. Legal customers with no desire to have that piece of shit malware on their PC are screwed as well. They stealth patched it before release a few hours after the pirates detected it and then spun a bullshit tale of how it was intended as DRM.
If I recall correctly it was more along the lines of being unable to glide from gargoyles. At all. If you did Bats would fall down and die from poison gas. Not sure though.
Damn, that's hilarious. Seriously, if I was making an anti-pirate measure, it'd be some clever fuck-you to the player. And then, anyone who goes on the support forum to complain about it, bam - pirate identified.
As for the free-roaming after the big fight, s'cool, I want to play it over anyway. It's fun.
I want to talk about the Scarecrow segments, because they were awesome. After the first two, I thought that the whole "hey you're actually playing a videogame" aspect was completely ignored and that the command prompts kind of cheesed things up. Boy was I wrong. But for the sake of entertainment, I will present my reactions in interpretive recollection.
As soon as I heard Batman coughing I knew what was coming. It's pretty obvious after watching a room full of guys tearing their skin off that I'm about to get head-fucked, but I was cool with it.
"Coughing? Shit, here we go. What kind of dickery am I in for? Cutscene maybe? Well, I see the camera's tilted, that's a start. Oh hey, Gordon's in trouble. And dead. But wait, he's not identified. And Batman's eyes are glowing. Aaand, now we get Crane's attempt at doctor humor. Nice callback to Batman Begins."
So we get to the morgue. I know something crazy has to be coming up, but nothing happens. Sure, the doors start flapping and whispering, but I was expecting a zombie attack or something.
"Alright Crane, I don't have time to play with you right now. I'll just be leaving..." Walk through door. "...Dammit. Fine, I'll have your little fun. Let's see, bodybags, oh boy. Parents maybe? Yep, there's mom, and dad. So who's behind Sack #3, Gordon? Dick? Me? What the crap... Hey, nice makeover Crane, looks good. So what's the gimmick this..." Turn around to see-
NO THUGS
GIANT SCARECROW
SIDE-SCROLLING PLATFORMER
FINAL DESTINATION
"Oh balls, he's huge now. And he's got laser eyes? Fantastic."
"Coughing? Again? Oh dammit, why. The story's finally getting interesting and then-" Hallway of Doom
"...Fucking Hell, that's cool. So what do I get at the end? Hey, nice, more backstory with Gordon. Is this canon? But seriously, Bruce, get over the parents already. You're like forty five man, it's just sad."
The second stage's action parts were the comparatively blandest, except for the skeletons. I want to, nay, have to believe they were an oblique commentary on how, thanks to the indispensable nightvision AKA Detective Mode, you spend most of the game beating up iridescent skeletons.
And the belltower exit was just great. "Hey Bats, I don't think they heard you in fucking Metropolis."
"Homicidal wildmen, mutant plants, gorilla warriors. Man, a dozen guys with guns seems downright quaint now. Oh fuck yes, coughing. What's it gonna be... AH WHAT THE FUCK? Oh you piece of shit drive! I knew I shouldn't have gotten the off-brand external. Oh goddammit I'm gonna be pissed if..."
The Scarecrow Signal
"Ooohhh. Oh... OOOOHHHH, fuck yes! Oh yeah, it's motherfucking Joker time! In your face, everyone who bought a Playstation. Hey, Scarface for the warden? Saw I presume. Nice touch, I was wondering why they resurrected that bullshit concept. Oh man, I can't wait to- Hey, what's this shit, why am I Batman again? I don't want to be Batman, I want to be Joker now! Hey, what the fuck is this-"
Move the mouse to dodge Joker's gun. Retry? Cancel?
"...Wow, that's some serious bullshit. I'm supposed to see that coming? Alright Psycho Mantis, if you want to play this game, we'll play this game. Man, what a fucking mood kill. Just gotta hit Retry and..."
R.I.P Bruce Wayne
"Hey, what's this? What the Hell is... Oh damn. Wow. Fine, I admit it. Well played Mantis, well played."
Were I in charge, I might have done things differently, like meld the "action" parts more to the real-world areas, maybe introduced some command-prompt dickery earlier on. But if anything, the least satisfying part is that you don't get to kick his ass in the end. One more reason to hate Croc.
