Sausalito Party: FWIW, I cleared it on the 2nd try. I set up some traps, knowing where I should hide and which paths enemies would likely approach through. It was nearly easy, but it is not a good mission. All kinds of meta-knowledge about what's going to happen and when are needed to clear it, or Marcus is turned into prosciutto.
I can't remember the order, if it was before or after that, but the spiritual opposite of those missions are the ones where Marcus gets AR supplemental information about where the enemies will be and from which direction the cars will arrive. In that sense, the immersion is great – ludonarratively it makes sense. It's less fun to repeatedly die, unsurprisingly.
Fantastic game; it's missing… something to put it on the same tier as Red Dead Redemption or GTA V, but I'm not sure what is missing. Honestly I like the writing better than GTA V; the game knows what it is, and isn't trying to prove something. It's heaps better than the first game, keeping everything that worked, and getting rid of tons that did not.
