Okay, final post on this because this is not the hill I want to die on in regards to this movie. There are SO many worse problems with it and I don't care that he lifts it from Arkham games. I just can't personally assign him creative credit for it. Which is bizarre that this is what got this thread in a frenzy, because me not personally giving Snyder credit for the scene seems like it'd be a pretty small issue to everyone involved. He won't care, those of you that seem to agree he lifted it from the games care more about that you just got a good fight scene, and I'm not saying it's a bad fight scene, or that it should be removed or anything like that, so....I don't really get it. All I'm saying is that I think Rocksteady is the one who truly deserves the credit for it's creation, because they are nearly identical. That's less a criticism of the movie itself and more me just saying Snyder could have been more creative about it. Which shouldn't be a controversial statement, I think.
Anyway, the main defense seems to be "Yeah, it's really similar to it, but not completely." Well, yeah, most people who copy stuff don't literally completely copy things perfectly. Not to a complete degree, just a significant one. Eragon was not a literal copy of Star Wars, but the general story was similar enough that people did notice it basically was star wars. Avatar isn't literally Ferngully, but the number of parallels you could draw obviously make it derivative.
So with that in mind, I've gone through the fight again to make double sure that I wasn't talking out my ass when I said that the fight could be significantly replicated in the actual games, and I wasn't off. There are differences. In the opening of the fight, Batman uses a gadget that disables like 6 guys by making their guns explode. Batman can only disable, at most, 4 (I think? It's been a while. It's either 2 or 4) guns at a time and it takes the gadget a while to do it, and they use some kind of magnetic wave rather than a bomb, but the function of the weapon is the same and you can create a similar set up, it just takes slightly longer. He uses the batclaw to grab a thug so he flies toward him, then punches him away, with the difference being that in BvS, the batclaw goes through the thug's actual body rather than grabbing and letting go. The most significant difference I think is that Batman uses his enemies weapons against him, including guns, where he otherwise just breaks them.
Watching this scene, going step by step, it's really is mostly replicable in the game. Some of it would be hard to pull off all together, since you can't account for thugs being in different locations, but most of Batman's actions and counters to the enemies? Yeah, mostly. I would say it is to a significant degree. If you disagree and think those differences are significant enough to say Snyder made it his own....you know what, fine, you do you. But you have to be pretty aggressively contrarian to deny the significant similarities here.
