i think it would be really good to play as black cat. However i probably wouldn't play as her much either, but it depends on what sort of gameplay mechanics she has. I would like to be able to play as her and have missions to do, for example because she is a cat burglar (not actually a 'cat' burgular) haha, i think it would be good to have to silently steal something valuable and expensive from one of the main villians in the game or side villians. Also jump across buildings, harrass people etc lol What trailer does she look like a playable character in by the way because i haven't seen it?
i also hope Peter Parker is playable as well. Yes i know that you only play as him once in the game but i mean like DLC where you are playing as Peter and a crime occurs so you change into your Spidey clothes and other things, or or or or......... DLC mission where you are playing as Peter and you are taken hostage in a building with a bunch of other people and they request for Spiderman and if he doesnt turn up, then the hostages will die. I think this will be a unique level to the game add ons because you would have to get free from being taken hostage without anybody noticing before time runs out! Just like or similar to the Spiderman new nimated series voiced by Neil Patrick Harris in the episode 'Tight Squeeze'. That was the best tv series ever, oh and the 90's series voiced by Christopher Daniel Barnes.
