Customers are buying Microsoft's Xbox One and Sony's PlayStation 4, but they appear to be buying them for different reasons than the one that powered previous console launches.
Though each company has sold more than 3 million consoles since their November launches, those sales have not created a surge in game sales or even a hit title for either console.
Considering COD, Madden, Fifa, BF, etc. are the most popular games every year and those games are on next-gen consoles, maybe people just wanted graphically improved versions of those games, in which case, games are driving the next-gen console sales.
Good grief, was that an ad or a self plug?
There was really know HUGE heavy hitters on launch for either system. What I mean is a game that EVERYONE wants to play.
That game that even non gamers be like...whats up with (insert game here).
Take a game like GTA V....imagine if that launched on xbox one and PS4 ONLY (It would never had happened) but sales would have been much higher because that is one game that many would by a system for. (I know I would!!!)
I feel that both systems will build there install base and over time....when more and more make the jump over game sales will go up.
Im sure having many games on BOTH systems are effecting game sales.
I can imagine many are saying....why do I need to spend 400-500 plus games when a lot of those games are on my current system (Assassins Creed, COD, MAdden, FIFA, BF4 etc etc).
When the 360 released there was nothing on launch and for many months after that made me want to make the jump from my PS2/xbox combo. I suspect that is true for this new gen as well.
Both consoles enjoy about a 2.5 or better attach rate. And that's for physical games. This, as someone else mentioned, likely does not include the upgrade promotions from last gen versions of games.
It most assuredly does not include free to play and other digital games. For example, I have 3 digital PS4 games (thanks to PS+), but I don't even have the system yet. Flower and DC Universe would make five digital games, while I'd have just Knack and Killzone physically. My measurable attach rate, then, would be just a 2, but the actual rate would be a 7(actually more than that, since I forgot about Warframe, and probably something else, too).
With these things in mind, I think your "concern" should be laid to rest.
