What caught my eye the most is pretty dumb physics. It is possible to get up on a hill with pretty much any vehicle, the bikes seem to be "glued" to the road, also cars almost always land on tires after any kind of jump which is pretty irritating as one can see the car stabilising itself in the air... All-in-all it's fucking Saints Row, not GTA anymore in these terms. Cars now hardly get wrecked. The best and most realistic car wrecking opportunity we had in IV, now it's gone. When one goes around 150mph and crashes into the wall the car would seldom get considerable visual damage.
What I actually liked is the city itself, how dynamic it is and of course the story is amazing.
Now the map:
This was actually true huh.
The map doesn't even seem to be bigger than SA, which is at least slightly odd because rumors said it would be as big as nigga mothers' ass in da hood. Anyway, the game is overrated as hell.
