I'm totally fine without a villainous team. For one, I don't think every series needs a villain per se. Sometimes we just want a story. You can have conflict (rivalry, in this case) without a clear cut bad guy. And more often than not, villains are half ass tossed into stories just because someone thinks "oh right gotta have a bad guy!"
Second seeing as the time this game came out. Let's be real, 2016 has been hell on the world. I will gladly settle for a game that takes people out of the shit of the real world without a villain when we've been dealing with enough this year -- and other years past and more to come in the future.
