Eh, it kinda makes sense, to me. PC has always been more of an inclusive gaming thingie: you download the game, it fuckin' works. Then, Steam gave everybody and their dimwitted aunt the idea of centralizing distribution of their games; EA's got Origin, Ubisoft has uPlay, etc. Some because they needed/wanted launchers for option customization and shit, but a lot just because they wanted their own clubhouse. Then comes along Epic, trying (and failing miserably) at aping Steam...which was fine because Steam has a tonne of mush-mouthed, buck-toothed huncback cousins, nowadays. Then, Epic got greedy and signed a bunch of games that were gonna come to the quasi-monopoly platform that provides the superior service (what fucking e-commerce place doesn't have a fucking shopping cart?) as timed exclusives.
Honestly, I've been leery of this kinda shit since Steam started hosting things other than Valve's own games. Having a unified launcher and platform for your own shit is fine, but it always struck me as kinda worrisome when they started hawking other people's shit, too. Once again, I was fuckin' right to be concerned, because now the anti-consumer bullshit that are "exclusive titles" is trying to infest the PC environment.
