1) Lumberyard license was signed on April 30th, 2016
2) they switched to that license (from the Crytek one)
3) they used the CryEngine code that's part of Lumberyard
1) 12/23/17 press release (which Ortwin refs in his affidavit)
04/30/2016 - LY license executed
08/25/2016 - Alpha 2.5 release
12/23/2016 - Alpha 2.6 (LY switch) release + LY switch announcement
Don't forget that throughout their LY evaluation from 2015 to the 2.6 release, they never disclosed any of it to backers. Not even once.
They lied. It's really that simple.
All this in a bid to sidestep the issue of using CE for two games, instead one; while claiming SQ42 is part of SC, and so it's covered by the ONE license
Note that the trial date is set for 03/24/2020
