I wish there was less emphasis on the gunplay, because the more I play it the less I enjoy the gunfights. I was playing Logan's Shadow on the train this morning and was trying to figure out why that style of stop-and-pop felt more solid. I think it's chunkier gun sounds combined with easier aiming but I'm not sure; aiming Drake just seems kind of fiddly, even when I doof around with sensitivity settings. I think it has more potential as a platformer (thanks to its animation engine) than a shooter.
BTW, I wish more games supported DTS 5.1, it's so rare to see this while playing a game:
