In any case, if you've picked it up and haven't beaten it go beat it. Perhaps he'll be back when his son is good and raised. I'm sad the leader designer has apparently retired in some capacity, but this is also a pretty strong title to go out on. Here's some of the concept art for consideration. That might be more a marketing lament on my part at this point though. It has the occasional weirdly art deco statue here and there (Why is there that one dedicated to your father basically crammed into the ceiling of the hardware labs?) but it doesn't commit in a way that makes me think people will be able to look at a screenshot of it a decade from now and go "That's Prey!" It needed a more iconic look and gimmick to stand out more. Those have a really strong, recognizable aesthetic that I'd say Prey lacks. Especially compared to similar titles like the Bioshock games or Alien: Isolation. If I had to lay one fairly major criticism against it, it's that the art direction isn't that memorable or cohesive. I imagine the reasons will be varied too scary, too hard at the beginning, not weird enough, not enough plot or scripted scenes. It's a real interesting game, but looking at the achievement stats it doesn't look like a lot of folks really stick with it for long which is a real shame.
I'm surprised at how reactive the game was to the things I did as I played, and how it parsed them in the ending in a way that really encourages you to play through again in a totally different style and mind set. Just beat a do-everything-I-can-manage first run of Prey, going for every side objective, every achievement, delved into every nook and cranny.
