Canonicity of the 2 first games
Well, i found this: https://www.vg247.com/2010/07/27/eidos-montreal-deus-ex-human-revolution-a-reboot-of-the-franchise/
And now i don't know if they say "reboot" in order to attract the attention of new buyers (Since it's before in the chronology) or if it is literally a total reboot and DX1 and IW are no longer part of the Canon. Anyone knows the answer?
