It was nothing different than the demo they showed at e3. They should have shown a different level to keep the momentum going...but i'll give it to jimmy fallon as he's the only talk show host that showcases videogames often.
Make no mistake - I do appreciate what Jimmy Fallon is doing with videogames and I love his over-reactions to it. However, it does make me cringe everytime he tries to play a game so amateurishly. I really am scared what would happen if he would try something a bit more complex like the TLOU.
I wanna see the open ended environments they have been talking about, damn it!
This looks like the beginning of Halo 3.
