There is something ridiculously joyful about just running around slapping people, I know it's immature but it really is a wee pleasure getting away from stuffy storylines and games that try too hard. I've noticed the gangs and police are on your case a lot quicker in this, doesn't take long before you're being hunted from all angles. I've noticed some nice wee glitches, one like the 'worm' glitch in Battlefield where folks have extended bodies/necks and they start to go all crazy with flailing limbs, looks daft but I do laugh.
Not played too much of the story so far but liking that upgrades can be bought to keep you going throughout the game, hopefully there are more than the ones you can see from the off though. Can see this being my go-to game when I've got a wee bit time to spare and just want some mind numbing fun
