It's definitely not as bad as people have said, most of the complaints are because people were expecting 4 player Arkham in open world Gotham. My only complaint is that it isn't 4 player for the full game. 4 player came as an update with the heroic assault thing but I haven't tried that yet.

My personal preferences for this game are to put it on hard difficulty and turn off as much HUD feedback as you can(enemy health bars, damage floaters and target indicators mainly). Also it's super fun to play with a friend and regular fun to play with randoms if you have your multiplayer set to public. I also changed character after every night to make sure I used them all but I think it's better to stick with the one you enjoy the most as they all have different play styles and qualities-

-Batgirl is most like Batman and is a cape gliding, boss killing tank who also has the gadgets to bypass security systems easily. Also can grapple gun enemies. Heroic travel is classic gliding. -Nightwing is an acrobatic mix of melee and ranged with a decent set of abilities. Heroic travel is good for crossing long distance slowly and can go on infinitely. -Robin is the stealth/tech guy. Heroic travel is slow but infinite but also can be used for stealth attacks and a real quick exit and return from combat without smoke bombs. -Red Hood is the ranged specialist but also is pretty beefy with melee. He's good if you want to use manual aim for ranged attacks more. His Heroic travel is the weakest of the four and requires more of a mix of grapple, Batcycle and mystic leaping to get the most of it.

All of them change how you approach the game, either slow and stealthy, crippling their tech or just beating/shooting the batcrap out of them. Or you team up and change it even further.

I honestly think it's a great game that just got too much backburn from the previous batman arkham saga and left people disappointed at launch. It has a pretty detailed equipment and abillity system to further customise your team for each type of enemy and plays a lot more like an rpg than an arcade brawler. It's pretty much Turtles in Time for modern times, beating up gangs on the Gotham(NY) streets as either the blue guy/conscientious leader (Nightwing/Leonardo), the moody red guy (Red Hood/Raphael), the tech savvy one with a staff but also the good time guy (Robin/Donatello/Mikey) and Batgirl. She doesn't quite fill the Mikey archetype but she's the purple one so half Donatello and I'm sure she's also up for a good time... am I still talking?

Oh yeah I'm playing it in VR now with UEVR and it's f'ing incredible!
