My favorite game of all time is Arkham City, by far, this game is similar in many ways but still finds a way to suck, the following may contain some spoilers.
They managed to screw up the hand to hand combat, much more glitchy.
The story is too straight foward, you go from place to place and fight 6 of the 8 assassins, no deadshot or shiva. (And you fight Bane 3 times, and ond boss, electrocutioner, you literally just press X)
It's not an Origin story, at all. (OHHH but there's a 20 dollar DLC origin story so it's ok!!! Greedy pigs)
"8 assassins after your head, what are you going to do?" Yet it's only 6 assassins and they're not even after me, you go up to each assassin and fight them, they never hunt you.
It shows hints of things that could be good in the story, but fail hard, like when Bruces identity is breached and Alfred is killed, though being a prequel we knew he'd live. Bruce revives him, leaves, and takes NO more precautions to his identity being breached.
Glaring plot holes, Batmans suit and gadgete are much more advanced before Asylum and City, Bane only loses his memory after taking titan, unlike everyone (later in time) that takes titan dies etc.
The ending was god-awful. Easiest boss fight ever and it abruptly ends.
They recycled many things from Arkham City yet found a way to make them suck, such as the combat system and map
Many many many bugs, saves getting corupted, black screens, dialogue issues etc. Game was clearly rushed.
Arkham Asylum: 8.9/10
Arkham City: 10/10 (how can anyone disagree? It's flawless)
Arkham Origins 6/10
