See, I can handle a linear game if it's done right. Really good gameplay, or something unique and fun, or both. But Warfighter is just another bog standard modern war FPS that relies on pretty graphics (at least on the surface) to attract people. Outside of the lighting and explosions and the big setpieces that you can show off in trailers, the graphics are actually kinda mediocre and tend to suddenly pop in. And it can get pretty glitchy sometimes, which Dan is always good at finding.
Some of the most hilarious stuff is the lack of paths. They do the Battlefield "Turn back or you will be killed" thing if you ever try to take an open path that's not the one the game wants you to take. He kept trying different paths that are really wide open and look like a way you can go, and then game literally threatens to kill your character if you try to use them. And it gives you so little time to get back that if you try to sprint down one of these pathways, you'll be milliseconds from not getting killed by the time you realize your mistake and run back.
