Yes you can, you seem to be confusion reality with fiction BASED on a reality that is really fantasy.
Video games are all fiction, comics all fiction but you can have realistic elements that make sense within that source of fiction
Besides, a lot of things on your list are very subjective. There's good reason for a lot of that MK explains via the story.
I really don't think anyone here believes MK, SF, Injustice etc=can really happen. lol
I disagree respectfully, sure there's crappy music of every genre. No argument there, but it's obvious the Disturbed video from MK 9 trailer worked a lot better(talking from overall reception) Pretty much everywhere I go with this trailer someone says somethiing about the music, and I have a ton of friends who love rap that even told me "this song doesn't go with this trailer well". So go figure. I personally don't care THAT much, my opinion it doesn't flow well but I won't judge the game cause of it like some people have said or made assumptions "omg they used rap so that means shitty music in game?!" no lol that definitely isn't me. I do agree though that some people make a really huge deal out of and same with the "omg female man chins, nooo!" thread. Like who cares? These guys aren't going to jerk off to these video game chicks right? lol Why do they care THAT much?
That's cool, my best friend is a huge rap fan didn't like it is more of an Eminem guy but he did say this video probably boosted Wiz's career having 3 million views always helps no doubt. But yeah I mean the overall important thing is that the trailer, game looks sweet so I look forward to it.
