On a serious note, this is what worries me. What if bigger new IP flop? Remember PS3 first year? Heavenly Sword, Folklore, Lair, even Uncharted. All sold like crap. Must be more but can't remember. Only Uncharted survived because of the long legs that games had. Plus bundles and gamers spreading the word about it.
It took years to establish it. It is going to be very interesting. I know I will be supporing Sony, even for a games that don't turn "incredible".
Then there will be inevitable effects on the people behind them. SCE will not have many mid-sized games this generation as Shuhei has already stated. This means you have mostly big titles, digital titles, and some mid-sized titles. Some of the digital titles will be good efforts with decent budgets, but the idea is for them to be small risks and hopefully for the brighter titles to become really successful. The mid-sized titles will be more careful efforts as they're on neither end of the spectrum and pose a bigger risk than the smaller titles. This then leaves the big productions. Some of these titles will have nothing to worry about like Gran Turismo, Uncharted, and other Naughty Dog games. You also have God of War, and SSM's other project which should hopefully catch on.
The problem is you also have various other studios like Guerrilla Games, Sucker Punch, Media Molecule, Evolution etc. Their titles aren't guaranteed for success. The other project GG is working on, or Sucker Punch will end up working on, aren't guaranteed either. If you're pumping the money in, there needs to at least be a certain level of success. Now granted with Naughty Dog, Sony Santa Monica and Polyphony Digital being very successful, there isn't a huge amount of pressure on the other studios, but there is still pressure to perform. Ideally, SCE wants all the big titles to perform really well. Not everything has to be Gran Turismo, but pushing 3-4 million even? At the least, that needs to be done.
Part of the reason why Infamous Second Son was delayed was to give the team more time to polish it, and to position it away from launch which has the likes of Watch Dogs, Assassins Creed, Battlefield and Call of Duty all ready to fatality titles. With there being less mid-sized titles, and mostly big productions, it also becomes important to position them correctly with the right marketing push.
2014 should be a good year. 2015 will be an even better year. Beyond that, I can't really say, but there are some big games on the way with some being new productions so hopefully they find success. The problem is third party productions will start rolling in more consistently too, and whilst not all third party games are big sellers, there are bound to be a couple of unexpected surprises in addition to some of the existing big hitters (COD, BF, Fifa, AC, ME). That just creates increased competition for first party titles.
Even Prince of Persia will be making a return. And Ubisoft has Watch Dogs and Assassins Creed too. EA is readying Titanfall, which will also end up on PS4 eventually so will ultimately be competition. They also have Mass Effect and probably other planned projects. Activision has Destiny, and other planned projects. Rocksteady has their Batman. Square Enix has Final Fantasy, Kingdom Hearts, Tomb Raider and their Eidos side is preparing another new IP. There is a lot of third party content. Not everything will be big, but some of it is big enough that it presents a significant choice to consumers as they're not going to buy everything. There are a lot of notable games. Exclusives do have the luxury of commanding extra attention since they've become a chest thumping exercise, but if the game itself doesn't really knock it out of the park, it can tarnish the franchise. This means future installments aren't as successful either which creates a bigger problem.
This is why new IPs, although indeed great, are a risk since the investment needs to be returned, and making them at the expense of existing popular franchises isn't necessarily a good thing. It's also why people are expecting a new Uncharted, God of War, or The Last of Us. You know they're going to come at some point. These titles carry recognition. This doesn't mean they're the only titles, but they're necessary to help prop up other new IP and bring in the money.
