skeletonbow: It appears that GOG is developing Galaxy client and services because they perceive the need for such both from the game industry (publishers and developers) and from gamers themselves, but they're doing it in such a way that makes all of it optional to the end customer and not a requirement. It's more of a "we now offer this useful software functionality to you also and hope it makes your gaming experience better if these are the types of things you've been wishing you had optionally available" to gamers, and "we now have these services available for you to enhance your software with without having to implement all of this functionality on your own, in hopes we can encourage you to also support our distribution platform instead of only distributing your games on Steam" proposition to developers/publishers.
In other words they are responding to increasing demand for these services/features both from gamers and developers/publishers but doing it in a way that makes it all entirely optional and up to the customer to decide how they want to experience their games. There seems to be no plans on making any aspect of it mandatory, and no good reason to believe that will change in the future from anything they've said so far. So by definition of what they've got planned for Galaxy, nothing that is made available for Galaxy would end up being Galaxy exclusive and it doesn't appear that they have any intent to try to do that anyway.
A game of any kind being Galaxy exclusive (FPS or otherwise) would go against the whole idea of giving gamers the freedom to choose how they play their games by simply substituting one exclusive way of doing things for another exclusive way of doing things.
Every big name studio out there making any AAA game is realistically going to be targetting the Steam platform or Origin or Uplay long before they'd remotely consider Galaxy. CD Projekt RED is the only company I can think of that might even theoretically have an incentive to create an FPS game with Galaxy multiplayer being a priority but quite frankly they are a game developer like any other out there and they make more profit from their games being available on Steam than from their own store too. They wouldn't spend millions on an FPS game and make it a Galaxy exclusive bundle to try to popularize the Galaxy platform or GOG unless they were comfortable with doing an extremely risky move that could collapse their entire business overnight.
Let's face it, with the massive budgets that go into any top selling big AAA games out there nowadays, especially FPS games - if even one game from a studio becomes a big flop or otherwise does not sell well once released, it can completely destroy the development studio or even the publisher and cause them to go out of business quick while the rest of the saturated marketplace swallows their dead carcass whole and lets out a big burp.
Personally I'd start getting pretty worried if I heard that CDPR/GOG were planning a big name huge budget FPS game to be GOG and GOG Galaxy exclusive to try to popularize the service. I'd be thinking "are they nuts? If this game flops and that is the most likely scenario, the entire business including GOG could collapse... time to re-download all of my games now while I still can..."
Would I like to see big name AAA FPS titles on GOG with or without Galaxy multiplayer etc? You betcha! Exclusively? Not really, and that seems very unlikely and unrealistic no matter who creates the game - either the incentives are not there, or the risks are far too high compared to other options that are available which are much more highly viable.
The only way we're likely to see an FPS game show up here that becomes uber-popular is if it is a small indie title that comes out of nowhere suddenly and develops a massive underground cult following of popularity of epic proportions. Such a game is highly likely to target itself to Steam though as that's ultimately where the big money is in the business game too so that chucks exclusivity out the window also.
I never said nor would I want an FPS that's GOG exclusive. I merely think that a solid FPS shooter offered by their service would be a good idea. It would not only satisfy many of us (I might be wrong) but, it would also bring new people in to the community.
Vheom: I think the new Unreal Tournament is a match made in heaven for the GOG Galaxy.
I wouldn't doubt it. It could work, if it used its own system. From what I understand, its also F2P.
