I don't know if there is already a list compiling games that have little call outs to Ryan, but I figured if there isn't one, there needs to be. This is by no means an exhaustive list, since I am not omniscient and there are many games that I haven't played and am unaware of. If you know of a game that has a tribute and it's not on this list, please let me know so I may add it.
This game has an achievement titled Forever Remembered in honor of Ryan. The developer put it there as a tribute in thanks for Ryan giving this game the spotlight which directly affected the games success.
Mr. Mooear himself created a tribute bloodline in honor of Ryan.
Ryan is listed in the Special Thanks section during the credits of the Burial at Sea Episode 2 DLC.
Ryan is listed as Bryan Davis in a special In Memorium section at the end of the credits.
There is a statue of Ryan called the Monument, and if the player stops at it for a minute or so and achievement pops called "It's Tuesday."
