Let's get this clear.
In Batman: Arkham Origins, batman is still young. Bruce Wayne is kinda baby-faced. You don't see many of the big supervillains.
BUT, these few drawbacks don't make this game boring at all. This game lets you know about many of the villains in the Batman universe, which you might have never even heard of before, for example, Mad Hatter, electrocutioner, copperhead, Shiva, etc.
You also get some new features. Batwing is one of them. Now don't get too excited. Batwing isn't playable. it's just a method of fast transportation. Still, cool, right?
A few new gadgets have also been introduced, although not all of them have been properly executed in the game.
One awesome thing is that there are LOADS of usable Batman's suits.
Overall, it's a really good game. And being a fan of Batman as a comic character than a game character, I liked the thing that a lot of comic references have been made in this game.
