The Zombie Apocalypse is getting old. Why can't we have an Alien Apocalypse survival game? Exact same premise but the enemies are aliens. You would still have to go scavenge for stuff only now you could also get some nice alien tech too. People just like the whole survival apocalypse aspect...I don't think it matters if the enemies are zombies, aliens, or zombie aliens.
I am very optimistic about this. Valve has clearly been working very hard for a long time to roll this out successfully. They are directly challenging Microsoft and Sony in a HUGE way. My guess is the people at MS and Sony are getting a little worried.
