I think there are more possibilities than simply hoarding. A game might be conceptually interesting enough that I am willing to toss a few dollars to the author as a show of support for their effort (particularly when the discount reaches >75%) even if I know full well that it will likely never quite reach the threshold where I find it interesting enough to install it and try it out. For other games that are mostly story rather than gameplay, I may already have experienced the content elsewhere; e.g. for Slay The Princess, I watched a playthrough by an online streamer and found the experience interesting enough to purchase the game as a show of support to the creators.
