This is the only rationale I can come up with for the game development policy: AGS hasn't produced anything in 8 years and what they have in the pipeline looks disappointing so...cross your fingers and hope one of your employees makes the next Minecraft.
Heh. I worked in Amazon Games for a bit. It was a very common question. Along with, "What games have they made?" (Breakaway a 'sports brawler', The Grand Tour game a tie in for the show, New World an mmo about being a colonizer, Crucible a third person shooter.)
