Well I think it is safe to say that the early days, even till as late as this month, were a bit stagnant. There were launch titles such as Assassins Creed 4: Black Flag (a decent game in its own right), Lego Marvel Super Heroes (a really fun game even after the main story), and DeadRising 3 (a promising game which quickly loses its novelty).
Then came this beast.
It is safe to say that this game has single-handedly saved Microsoft's and Xbox's bacon during the launch window. You can go onto any leading video games website and find that the release of Titanfall, and the bundle, has severely increased the amount of sales of Xbox One consoles. However, Microsoft still sit miles behind Sony.
Now that the launch window is over and PS4 has managed to shift almost double the number of units Xbox has they are well and truly beaten. But I believe - hard drive aside - as time goes on Xbox One will be the better system.
The entertainment side will come into its own, and has already shown a lot of promise, offering users early pass films, access to the best TV box sets etc. Even the apps will get better as time passes.
Believe me when I say, the future is green.
