Made the decision to get this on PS4, happy with it so far.
Only a few hours in, and the general run of play FPS is OK, but it did go completely to shit when I climbed up the altar cover in the cathederal - worse than anything I'd seen on PS3! Glad I waited for some of the patches before jumping in though.
Still, I'm enjoying the game. The built environment is lovely, the combat is improved and I still get to feel like a badass. Character animation is good IMO, and some of the cutscenes are astonishing...others not so much (altho at least they've got the teeth right). I'm really surprised at the inconsistency of the graphics TBH - sometimes it looks jaw-droppingly good, other times actually pretty poor.
Parkour is great, and the scale is amazing - I know Paris reasonably well, and walking around Notre Dame and the Left Bank along streets I know bought back memories of AC2 when I played it having just returned from a trip to Florence.
So far then - it's a Creed game, with all that implies. So far not as good as Black Flag or 2, but I'm not that far in, so who knows? I'm enjoying it, and that's what counts, right?
