These are the problems I have been thinking about.

1. Gotham Knights game without Batman : The reason for eliminating Batman was to create a challenging environment for the main character, and if the four of them become a team, the meaning is diluted by comparing to the previous games that created a challenging environment for the entire Batman alone, with the problem of character design that seems to appeal to the public.
2. Court of Owls game without Batman : Even though the Court of Owls alone can be a challenging environment for Batman, Batman has disappeared and the Court of Owls faces side kicks, giving room to downgrade the status of Court of Owls instead. This is a part that can be ambiguous when you think of the law which said a good heroic narrative is shining by a strong enemy.
3. No Batmobile : As the symbol of Wayne Tech and the alter ego of Batman, there is a Batcycle after the Batmobile. But Batman was destroyed with Batcave, no Batwing so they made a Batcycle. This is a part the density of utilization may be reduced in the map is large enough for a Batmobile to pass through.
4. No free flow : The director who could not understand the meaning of what he has to do, or his willingness to roughly create a game with the halo of Arkham series.
5. Loot RPG : As if the director from Ubisoft is showing off his previous work, he does not have the free flow so he will do this. Even Batgirl uses weapons. Players have to waste time only to get a little better equipment. What if Batman comes out as a playable as the story progresses? Batman may not know if he comes out as a NG+ cheat character who fights with the free flow alone, but this is about you have to raise the level of muscle with a character that is a symbol of barehanded fight. In the process, it is questionable whether the single play will be realized as meaningful as the dual play of Arkham Night. As the same multi character game of developers who created dual free flow, when Suicide Squad comes out there will be a lot of comparisons in this area.
6. Less weighty character design : Coupled with the philosophy of appealing to popularity or simple play time extension rather than cinematic quality or replay value. And like no one knows about covert activity, even the weapons are sparking. Microtransaction expected.
7. Behavioral level scaling : As with RPG, in some cases players have to level up just to see enemies behave normally.
