I have two that flip for my favorite depending on my mood at any given time: “There Will Be Blood” and “Blade Runner 2049”. They are both kinda slow and require attention to really appreciate, so probably my favorite movie to turn my brain off and have fun is “Mad Max: Fury Road”.
You’re correct on the two thoughts you listed. Wishlisting also makes the game more visible before release. For example, highly wishlisted games appear in the “Popular Upcoming” section, along with some other spots. This increased visibility before launch then feeds into the two points you made. I believe games that are highly wishlisted before launch are also more likely to appear on the frontpage right after launch.
