Doom Nukem because that's totally an original crossover and both Doomguy and Duke have exchanged verbal jabs at each other. Except that unlike Doomguy, Duke Nukem doesn't have a sh**ty attempt at reviving an FPS franchise. Doomguy on the other hand, obviously 2016 was made better because of him. But you all already know that.
League of Fighters because other than it being my 2nd attempt for EDGE, its actually a fighting game spinoff based on League of Legends and its a totally awesome spinoff that should continue to be in development and be released for everyone to play if Action-RTS isn't their cup of tea.
Call of Battlefield because even though DOOM 2016 and Shadow Warrior 2 have proven that the whole modern military shooter theme has already faced the facts that a great FPS should not try to be Call of Booty, Modern Military Shooters still continue to be a thing because of the $$$$$$$$$$$$$. Then again, I do legitimately like Battlefield 1, and I'm about to get my copy of Call of Duty: INFINITE WARFARE Legacy Edition so i have TWO GAMES FOR THE PRICE OF ONE, and Modern Warfare Remastered cannot be played without INFINITE WARFAREEEEEEE.
Titancucked 2 because EA pretty much cucked its own title by releasing Titanfall 2 within the same time period that Battlefield 1 (Also EA published) and Call of Duty: Infinite Warfare is at. Obviously Titanfall 2 isn't selling well when pitted against those Militeery shooter Jugglenuts, so EA pretty much just cucked Respawn Entertainment out of those precious $$$$$$$ but sadly, Titanfall 2 is actually a pretty good game. Please play it! I beg of you. Rem and I are begging of you. Titanfall 2 is actually a decent game and I'm actually dead serious on that.
