Something I keep bringing up in exclusives threads. Everything is an exclusive to someone that owns just one console. But that's looking at it from a consumer perspective to which I would say; of you want to play games, invest in the platform that has as many games as you are interested in. Simple as that. If u can afford to invest in multiple platforms and can justify such an investment, then go right ahead.
Now let's look at the Pub/dev. Its not about who gets to who first, or even how much money is put on the table. Its all about who offers the best deal.
Let's dig in. MS has intimately more money than Sony. But unless MS plans on deliberately losing money, that doesn't mean shit in the gaming industry. Here's how it works. When courting an idnie developer, or any kinda exclusivity deal, both Sony and MS come in saying the exact same thing. We will bankroll the marketing/localization costs of your game (basically think of anything that's not developer related) and in addition to that we reduce how much u pay us for royalties on each game sold.
Pretty simple when u think of it. But here's where it gets interesting.
That same deal means so much more when factoring in the install base of each platform. When accepting such a deal from on platform holder, devs will factor in with the potentially stand to lose by the time their game is ready for launch. So basically, Sony can walk in an offer up $20M and a 50% reduction in royalties. And MS would do the same. But the dev will know that their game could sell 100% more on the PS4 which means more money for them overall. So for them to go with MS, MS would have to cough out more money up front. The more PS4s lead over them grows, the harder it would be to cough that money up.
Now the platform holders..... pls let's not be naive. These companies are in competition with each other. So its important that they add as much perceived value to their console as possible. Best way to do that is by securing exclusives. The more of those you secure, the more reasons you give people to pick you over them and the faster your install base grows. Which in turn means more money, and in turn means more exclusivity deals cause with a certain sized install base, those deals pretty much pay for themselves.
