The Longest Journey: Still a personal favorite of mine. Requests can include any fantasy/science fiction/speculative work you care to imagine. Personal picks will be favorites of mine that include some sort of portal/transition-to-an-unknown-world element.
Wolfenstein: The New Order: I've decided not to do history lessons and instead open up requests to every World War II-era story out there. This can include real-life memoirs, fiction books, movies, shows and anything else with the Nazi regime and World War II as a significant part of the setting. Personal picks will be a few of the seminal classics.
Prey (2017): This replaces XCOM 2 since it's more in my wheelhouse and won't require me to constantly reload to get a better run. Requests can include any book/movie/show that features both humans and aliens, and personal picks will include some underappreciated favorites of mine.
The Witcher 3: Wild Hunt: Consider carefully before voting for this one, because I'll likely be at it for a year and a half at least. I'll also have to run things a little differently, creating hour-long videos to get through the game faster and bringing in guests so I won't have to edit as much. Requests will be the same as Longest Journey since I don't want to stick with fantasy for that long. Personal picks will be the entire Witcher novel and game saga, all of which I've already been through.
