As the guy explains, the difficulties in supporting all three platforms weren't apparent until later on in the development cycle.
Sorry but this is just a load of cobblers. If the devs were dead set on releasing the game for all three platforms from the very beginning, then why, pray, did they decide to release 35+ mins worh of gameplay that's clearly not representative of the final product without prior assessment of the consoles' computational power? Who in their right mind would've done that (except for Ubisoft and a bunch of other shady devs, that is)?
I'm not upset because the latest build doesn't quite match up to the trailers we've been shown. I knew the game wasn't going to look like that. I'm upset because the final product appears to look significantly worse than the 2014 Gamescom gameplay which, in turn, looked worse than said trailers. And that gameplay was running on a high-end PC, which clearly indicates anyone with a machine powerful enogh could expect simiar visuals form the PC version.
But now they announce that they had to scale things down "to the lowest common denominator"... Surely they could've known that not being upfront about the entire issue would backfire on them sooner or later, especially that you don't have to be awfuilly perceptive to notice a downgrade of such scale? Honestly, this makes Watch_Dogs gate almost insignificant.
