When talking about this game I find myself having to use the term "open world game" over and over. That's pretty understandable given the genre, but I wonder how common these games will become eventually. I mean we rarely get to use the term "levels" anymore in regards to "I'm on the last level of the game", unless the game in question is going for something pseudo old school. Games these days often seamlessly transistion from one level to the next, and they're usually divided into chunks called "acts" or "chapters" if anything.
2D and 3D had a similar transistion period back in 1995-ish when you'd go "3D game" about polygonal stuff. Nowadays the defining term of the two is 2D, because they've become the exception.
I was more or less convinced during the Xbox/PS2/GC era that open world inherently meant less fidelity, and not just in terms of graphics but also in world interaction. Spidey was sorta skidding all over the place, spazzing about, no matter how fondly recieved Spider-Man 2 was, and the GTA games.. well let's just say what they lacked in gameplay finesse they worked off in freedom, immersion, quantity and cinematic quality. Assassin's Creed was staggering to me precisely because it was for all intents and purposes an open world platformer with mechanics and interaction on the level of Sands of Time. Suddenly I realised what an absurd notion it had been that open world games would never reach that kind of sophistication.
Between games like InFamous, Assassin's Creed and this, it's abundantly clear that you can transplant the gameplay from the directed, focused kind of experience into a large "living" space intact, and with the scripting potential of missions within its framework, you can basically set up any degree of authored insanity, if that's your thing as a developer. Meanwhile, establishing a large, convincing, inviting environment lays a foundation for any number of return trips in additional episodes while prepping the next big entry. The Yakuza games make a habit of revisiting the same places over and over, with the addition of content and storylines, while the GTA episodes and RDR expansion quite literally did exactly what I'm suggesting.
So with new hardware making it easier to fit everything under one roof and open world games consistently racking up the lofty metascores, I wonder just how common this genre will become in the coming years. It goes without saying that there's never THE ONE DIRECTION gaming will take, so I'm definitely not suggesting that it'll supplant every other approach to an action/adventure video game, but it's somewhat telling that Assassin's Creed - especially with the later addition of tombs and an assortment of platforming puzzles - in some ways awkwardly overlaps the appeal of Prince of Persia (sans thematically) in a way that Ubi obviously struggle with what to do to properly set them apart.
