Really really really loving this, though I'm taking it quite slow (Hearthstone, Darkest Dungeon and err Ninty Badge Arcade are taking up the rest of my time). I'm towards the end of the Shanty Town portion of the game, I imagine I'm probably about a third or half way through the storyline maybe. The most enjoyable part of the game for me, apart from the visuals, is just traversing the world itself. It's very fluid and loads of fun. Not massively keen on the combat, I don't like the way they run up to you rather than stay in cover, but that's just a personal preference.
The collectibles seem a little pointless so I'm not sure I'll be too fussed getting the GPS caches or relics.
I'm surprised how short the tombs are. For some reason I expected them to be Zelda dungeon-like in length, but most so far seem to just be one puzzle/room. Nothing against that, it works well enough.
So yeah, awesome.
