I don't know -- I really think it is impossible to come up with a season pass that everyone would have been totally happy with. I think a lot of the people who are saying it's not worth it were expecting a single huge chunk of add-on content that is about 2/3 the size of the full retail game to "justify" the $40 cost of the pass.
But when I look at that above list, I have to admit, damn -- that is A LOT of DLC. Sure, maybe it is not all everyone's cup of tea, and not everyone will get what they want, but there is plenty there to appeal to most fans of most versions of Batman. Almost every live action era /franchise of Batman is represented, almost all of the most well-known movie Batmobiles. So many alternate Batman skins. Nods to the games that came before. So many other characters (playable only in the challenges, yes, but at least they're there). On top of that, there has been a genuine responsiveness from RockSteady to make unplanned changes to try to give the fans what they want -- even while faced with the challenge of fixing the botched PC release at the same time. They modded the challenges to make them closer to what the experience was in the previous games by reducing the blue walls and adding character-select. They saw the demand for a Nolan Batsuit and they're filling it (though, I kinda suspect this one was always in the cards).
Yes, the PC launch was completely screwed up, and the DLC out of the gate -- when viewed individually, isn't much to write home about. I can see why there's disappointment with this game not being the "ultimate" end-all Batman game experience in some's eyes -- I see complaints of lack of replay value and I'm impressed that people have played enough that that's an issue. It's gonna take me a really long time to get through playing all of this stuff just once.
I just want to express what I feel has become the dissenting opinion here: to me, cumulatively, RockSteady did an amazing job with this game, the breath of the DLC that has been released so far (and is scheduled to be released) and of course, with this entire series when viewed altogether. This game, and all of this content is a work of art. Well done, RockSteady. Well done.
Alot of this DLC though is largely what was included in other games. Challenge map characters, alternate costumes.
DLC needs to actually add something. None of these really do. Id pay £10 for all the story dlc and thats it.
The batmobiles are largely irrelevant; no battle mode rules playing almost the entire game. The skins; its not enough for replay value. They are released 3-4 months after the game is out. AC the skins were mostly already there. New game + I was in BTAS or the 70s blue and yellow. The rest I didnt bother with.
Challenge maps; its done in a poor way with the faux VR walls. Takes me out of it to be honest.
The DLC is alot of irrelevant content when Ive wrapped the game up twice but crucially unlike AC or AO; Ive no desire to replay the game. Jesus Ive finished City over 20 times, origins over 10 times and I still want to play them, AK doesnt make me want to touch the damn thing ever again.
