There isn't much that Volition didn't cram into Saint's Row IV. The design is a tombola of ridiculous things, a churning barrel of awesome nonsense that you randomly pluck fun from, and then give a child a teddy bear. Hmm, I over-analogised that one. Not that you shouldn't give a child a teddy bear, but if you do it after every moment of fun in this open-world nonsense generator you'd better have lots of bears and lots of children. And I'm about to make that unlikely scenario even more problematic with the Saints Row IV First Person View mod. It makes it even more fun.
It says a lot about SRIV that I haven't been hunting for mods for it, but this is worth checking out: it turns your ridiculous movement skills into a lurching, terrifying full-body experience. Imagine Mirror's Edge unfettered, and now imagine standing at the highest point in Steelport, looking down. It's vertiginous when you're in third-person, but when you're doing it from the first-person and you're looking down your chest and past your toes, a bubble of regret forms in your stomach acids.
They're ironing out some technical details with weapons and super powers, but the core experience ready and is splendidly sickening.
